Final Semester - June 2015

Heat is a form of energy which produces the sensation of warmth. It is total thermal energy of the body which is sum of kinetic energies of all the individual molecules of the body. It is transferred from one body to the other on account of temperature difference between two bodies. Joule found that when' mechanical work (W) is converted into heat (Q), then the ratio of Wand Q is always constant, represented by J i.e., Joule's mechanical equivalent of heat. \(J=\frac{W}{Q} \text { or } W=J Q\)   A measure of temperature is obtained using a thermometer that use Physical Properties which change uniformly with temperature, for example, in common liquid in glass thermometers, mercury, alcohol etc are used whose volume varies linearly with temperature over a wide range. (i) Define temperature and its significance. (ii) Define One calorie. (iii) How does a thermometer work? (iv) Name the two convenient fixed reference point for measuring temperature.

When solid is heated, the amplitude of vibration of atoms and molecules increases. Therefore effective interatomic separation increases and cause thermal expansion. Thermal expansion of solids are of three types: (i) Linear expansion (ii) Area expansion (iii) Volume expansion. Thermal expansion of liquid are of two kinds. Real expansion and apparent expansion that occurs in form of volume expansion. Thermal expansion of water is anomalous i.e., volume of given amount of water first decreases with increase in temperature from 0 °C to 4 °C and beyond 4 °C volume of water increases with rise of temperature. In thermal expansion of gases is more than solid and liquid but coefficient of volume expansion is dependent on temperature for gases. (i) On what factors does the coefficient of thermal expansion depend? Write its S.I. unit. (ii) Write the relation between the three coefficients of expansion  \(\alpha, \beta\)  and  \(\gamma\)   for solid. (iii) A body at higher temperature contains more heat. Comment.

(vii) State water equivalent.

States of matter viz: solid, liquid and gas are function of temperature and heat content. During the change of state of a substance, the exchange of heat takes place between the substance and surrounding. In this process temperature of substance remains constant. At certain temperature known as melting point. Both the solid and liquid states of the substance coexist in thermal equilibrium. Similarly, at boiling point both the liquid and vapour states of the substance co-exist in the thermal equilibrium. There are certain substance which on heating directly pass from solid to vapour state without passing through the liquid state. This is sublimation process in which solid changes to vapour state of the substance. Process of change of state depends on pressure and temperature. (i) Define triple point. (ii) Define latent heat of a substance.  (iii) What is principle of calorimetry? (iv) What is effect of pressure on the melting point of a substance? (v) State phenomenon of relegation.

Each rod has the ends at temperature T 1  and T 2  What is the condition that will ensure equal rates of flow of heat through the rods A and B?

All bodies emit heat energy from their surface by virtue of their temperature. This heat energy is called radiant energy or thermal radiation. The heat that we receive from the sun is transferred to us by a process which, unlike conduction and convection, does not require the help of a medium in intervening space which is almost free of particles. Radiant energy travels in space as electromagnetic waves in the infra-red region of electromagnetic spectrum. They exhibit the phenomenon of interference, diffraction, and polarization as light does. The emission of radiation from a hot body is expressed in terms of that emitted from a reference body (called the black body) at the same temperature. A black body absorbs and emits radiations of all wavelengths. The total energy E emitted by a unit area of a black body per second is given by E =  \(\sigma T^{4}\)   Where T - is absolute temperature of the body and a is Stefan's constant, if the body is not the perfect black body, then E =  \(\varepsilon \sigma T^{4}\)  , where  \(\varepsilon\)   is the emissivity of the body. (i) Determine the dimensions of Stefan's constant a from Stefan - Boltzman law. (ii) What is S.I unit of Stefan's constant? (iii) In which region of the electromagnetic spectrum do thermal radiation lie? (iv) Which device is used to detect thermal radiation? (v) When a body A at a higher temperature T 1  is surrounded by another body B at a lower temperature T 2 . Write the relation between the rate of loss of heat from body A and temperature. (vi) On what factor does the rate at which energy is radiated by a body depends? (vii) On which parameter does the colour of a star depends upon?

Thermal properties of matter case study questions with answer key answer keys.

(i) Temperature of a body is the measure of degree of hotness or coldness. It determines the direction of flow of heat when this body is placed in contact with another body i.e., hotter end to colder end. (ii) One calorie is the amount of heat required at a pressure of I atm. to raise the temperature of 1 gram of water through 1 o C. 1 calorie = 4.186 Joules. (iii) Thermometer is based on change in property of matter with temperature. Some common properties are: (i) variation of volume of liquid with temperature. (ii) variation of pressure with temperature. (iii) variation of resistance of metal with temperature. (iv) variation of thermo emf with temperature of a junction in a thermocouple etc. (iv) Reference point for measuring temperature are steam point and ice point of water at standard pressure. (v)  \(\frac{T_{C}}{100}=\frac{T_{F}-32}{180}\)   (vi) It is the temperature at which pressure P of gas would reduce to zero so also volume V of the gas. It is the lowest attainable temperature. 0 °K = -273.15 °C. (vii) Scale of temperature with its zero at -273.15 °C and size of each degree same as on the celsius scale, is called kelvin scale T K = t °C + 273.15

(i) It is a particular point on the P- T phase diagram representing a particular pressure and temperature at which the substance can co-exist in all the three states viz. Solid, liquid and vapour. (ii) It is the amount of heat energy required to change the state of unit mass of a substance from solid to liquid or from liquid to vapour without any change in temperature. (iii) Calorimeter works on the principle that heat lost by one body is equal to heat gained by other provided no heat escape from system to surrounding in any form. (iv) Melting point of a substance decreases with increase in pressure. (v) Phenomenon of refreezing of ice when pressure is reduced is known as relegation. (vi) The temperature at which the liquid and vapour states of substance are in thermal equilibrium with each other i.e., vapour pressure becomes equal to external pressure. Boiling point of a substance increases with increase in external pressure. (vii) On heating a substance, the change from solid state to vapour state without passing through the liquid state is called sublimation. e.g., camphor, iodine and solid carbon dioxide are sublime substance.

(i) In the steady-state, the rate of flow of heat is the same for all rods. If T 1  and T 2 are the temperatures at the junction points between A, Band C respectively. Then \(\frac{Q}{t}=\frac{K_{A} A\left(100-T_{1}\right)}{d}\)   =  \(\frac{K_{B} A\left(T_{1}-T_{2}\right)}{d}\)   =  \(\frac{K_{C} A\left(T_{2}-0\right)}{d}\)   Given K A =2K 1   K B  = K and K c =0.5K. Hence 2(100 - T 1  ) = (T 1  - T 2 ) = 0.5(T 2 - 0) and T 1  - T 2 = 0.5T 2 T 1  = 85.7 °C. (ii) Since T 1  = 85.7 °C, therefore T 2 = 57.1 °C using 200 - 2T 1  = 0.5T 2 (iii) Since the rods have the same lengths and the same diameters, the equivalent thermal conductivity of the series combination is \(\frac{1}{K_{e}}=\frac{1}{K_{A}}+\frac{1}{K_{B}}+\frac{1}{K_{C}}\)   =  \(\frac{1}{2 K}+\frac{1}{K}+\frac{1}{0.5 K}\)   K e =  \(\frac{2 K}{7}\)   (iv) Coefficient of thermal conductivity of a solid is equal to the rate of flow of heat per unit area per unit temperature gradient across the solid. S.I unit of (Coefficient of thermal conductivity) K is Wm -1 K -1 . (v) As  \(\frac{\Delta Q_{1}}{\Delta t}=\frac{\Delta Q_{2}}{\Delta t}\)   \(\therefore \quad K_{1} A_{1} \frac{\left(T_{1}-T_{2}\right)}{L_{1}}=K_{2} A_{2} \frac{\left(T_{1}-T_{2}\right)}{L_{2}}\)   \(\Rightarrow \quad \frac{A_{1}}{A_{2}}=\frac{K_{2}}{K_{1}}\)   i.e., the cross-sectional area of two rods must be in inverse ratio of their thermal conductivities.

(i) Stefan - Boltzman law states that E =  \(\sigma T^{4}\)   where E - stands for the total energy emitted per unit area per second. Thus dimensions of E = dimensions of  \(\left(\frac{\text { Energy }}{\text { area } \times \text { time }}\right)\)   i.e.,  \(\frac{\mathrm{ML}^{2} \mathrm{~T}^{-2}}{\mathrm{~L}^{2} \mathrm{~T}}=\mathrm{MT}\)  ,therefore, dimension of \(\sigma=\frac{\mathrm{MT}^{-3}}{\mathrm{~K}^{4}}=\mathrm{MT}^{-3} \mathrm{~K}^{-4}\)   (ii) S.I unit of Stefan's constant is Wm -2 K -4 (iii) Thermal radiations lie in the infrared region of electro magnetic spectrum. (iv) Thermopile is used to detect thermal radiation. (v)  \(E \propto\left(T_{1}^{4}-T_{2}^{4}\right)\)   (vi) The rate at which energy is radiated by a body depends upon. (i) the surface area of the body (ii) the temperature of the body (iii) nature of the surface of the body (iv) the emissivity of the surface of the body. (vii) According to Wein's law  \(\lambda_{\mathrm{m}} \mathrm{T}\)  = Constant. Colour of star depends upon its surface temperature.

Motion in a Straight Line Case Study Questions With Answers

Here, we have provided case-based/passage-based questions for Class 11 Physics  Chapter 3 Motion in a Straight Line

Case Study/Passage-Based Questions

Case Study 1:

When an object is in motion, its position changes with time. But how fast is the position changing with time and in what direction? To describe this, we define the quantity average velocity. Average velocity is defined as the change in position or displacement ( △ x) divided by the time intervals ( △ t), in which the displacement occurs:

Where x2 and x1 are the positions of the object at times t2 and t1, respectively. The SI unit for velocity is m/s or m s–1, although km h–1 is used in many everyday applications. Like displacement, average velocity is also a vector quantity. Average speed is defined as the total path length traveled divided by the total time interval during which the motion has taken place:

Average speed = Total path length/ Total time interval.

Average speed has obviously the same unit (m s –1 ) as that of velocity. But it does not tell us in what direction an object is moving. Thus, it is always positive (in contrast to the average velocity which can be positive or negative). If the motion of an object is along a straight line and in the same direction, the magnitude of displacement is equal to the total path length.

The velocity at an instant is defined as the limit of the average velocity as the time interval Dt becomes infinitesimally small. In other words

Note that for uniform motion, velocity is the same as the average velocity at all instants. Instantaneous acceleration is defined in the same way as the instantaneous velocity

1) For uniform motion instantaneous velocity is the same as

• a) Average velocity
• b) Average acceleration
• c) Instantaneous speed
• d) None of these

Answer: a) Average velocity

2 If velocity is constant then

• a) Acceleration is zero
• b) Acceleration is positive
• c) Acceleration is negative

Answer: a) Acceleration is zero

What is average velocity defined as? a) Total path length / Total time interval b) Displacement / Time interval c) Speed / Direction d) Time interval / Displacement

Answer: b) Displacement / Time interval

Which unit is used for velocity in everyday applications? a) m/s b) m s–1 c) km/h d) Both a and b

Answer:c) km/h

Which of the following is true about average speed? a) It is a vector quantity b) It can be negative c) It is always positive d) It describes the direction of motion

Answer: c) It is always positive

Case Study 2:

When an object is in motion, its position changes with time. So, the quantity that describes how fast is the position changes w.r.t. time and in what direction is given by average velocity. It is defined as the change in position or displacement (Δx ) divided by the time interval (Δt ) in which that displacement occurs. However, the quantity used to describe the rate of motion over the actual path is average speed. It is defined as the total distance traveled by the object divided by the total time taken.

(i) A 250 m long train is moving with a uniform velocity of 45 km/h. The time taken by the train to cross a bridge of length 750 m is (a) 56 s (b) 68 s (c) 80 s (d) 92 s

Answer: (c) 80 s

(ii) A truck requires 3 hr to complete a journey of 150 km. What is the average speed? (a) 50 km/h (b) 25 km/h (c) 15 km/h (d) 10 km/h

Answer: (a) 50 km/h

(iii) Average speed of a car between points A and B is 20 m/s, between B and C is 15 m/s and between C and D is 10 m/s. What is the average speed between A and D, if the time taken in the mentioned sections is 20s, 10s and 5s, respectively? (a) 17.14 m/s (b) 15 m/s (c) 10 m/s (d) 45 m/s

Answer: (a) 17.14 m/s

(iv) A cyclist is moving on a circular track of a radius of 40 m and completes half a revolution in 40 s. Its average velocity (in m/s) is (a) zero (b) 2 (c) 4π (d) 8π

CBSE Case Study Questions Class 11 Physics Oscillations

Case study – 1.

A motion that repeats itself at regular intervals of time is called periodic motion. Very often, the body undergoing periodic motion has an equilibrium position somewhere inside its path. When the body is at this position no net external force acts on it. Therefore, if it is left there at rest, it remains there forever. If the body is given a small displacement from the position, a force comes into play which tries to bring the body back to the equilibrium point, giving rise to oscillations or vibrations . Every oscillatory motion is periodic, but every periodic motion need not be oscillatory. Circular motion is a periodic motion, but it is not oscillatory. The smallest interval of time after which the motion is repeated is called its period. Let us denote the period by the symbol T. Its SI unit is second. The reciprocal of T gives the number of repetitions that occur per unit time. This quantity is called the frequency of the periodic motion. It is represented by the symbol n. The relation between n and T is n = 1/T. The unit of n is thus s -1 . After the discoverer of radio waves, Heinrich Rudolph Hertz (1857–1894), a special name has been given to the unit of frequency. It is called hertz (abbreviated as Hz). Answer the following.

1) Every oscillatory motion is periodic motion true or false?

2) Circular motion is

a) Oscillatory motion

b) Periodic motion

c) Rotational motion

d) None of these

3) Define period. Give its SI unit and dimensions

4) Define frequency of periodic motion. How it is related to time period

5) What is oscillatory motion

Answer key – 1

3) The smallest interval of time after which the motion is repeated is called its period. Its SI unit is second and dimensions are [T 1 ].

4) Reciprocal of Time period (T) gives the number of repetitions that occur per unit time. This quantity is called the frequency of the periodic motion. It is represented by the symbol n. The relation between n and T is n = 1/T i.e. they are inversely proportional to each other. The unit of n is thus s -1 or hertz.

5) Oscillatory motion is type of periodic motion in which body performs periodic to and fro motion about some mean position. Every oscillatory motion is periodic, but every periodic motion need not be oscillatory.

Case Study – 2

There are no physical examples of absolutely pure simple harmonic motion. In practice we come across systems that execute simple harmonic motion approximately under certain conditions.

Oscillations due to a spring:

The simplest observable example of simple harmonic motion is the small oscillations of a block of mass m fixed to a spring, which in turn is fixed to a rigid wall. The block is placed on a frictionless horizontal surface. If the block is pulled on one side and is released, it then executes a to and fro motion about the mean position. Let x = 0, indicate the position of the centre of the block when the spring is in equilibrium. The positions marked as –A and +A indicate the maximum displacements to the left and the right of the mean position. We have already learnt that springs have special properties, which were first discovered by the English physicist Robert Hooke. He had shown that such a system when deformed is subject to a restoring force, the magnitude of which is proportional to the deformation or the displacement and acts in opposite direction. This is known as Hooke’s law. It holds good for displacements small in comparison to the length of the spring. At any time t, if the displacement of the block from its mean position is x, the restoring force F acting on the block is,

F (x) = –k x

The constant of proportionality, k, is called the spring constant, its value is governed by the elastic properties of the spring. A stiff spring has large k and a soft spring has small k. Equation is same as the force law for SHM and therefore the system executes a simple harmonic motion.

Damped oscillations

We know that the motion of a simple pendulum, swinging in air, dies out eventually. Why does it happen? This is because the air drag and the friction at the support oppose the motion of the pendulum and dissipate its energy gradually. The pendulum is said to execute damped oscillations. In damped oscillations, the energy of the system is dissipated continuously; but, for small damping, the oscillations remain approximately periodic. The dissipating forces are generally the frictional forces.

The damping force is generally proportional to velocity of the bob and acts opposite to the direction of velocity. If the damping force is denoted by F d , we have

where the positive constant b depends on characteristics of the medium (viscosity, for example) and the size and shape of the block, is usually valid only for small velocity.

1) Damping force is directly proportional to

a) Velocity

c) Acceleration

2) Oscillations due to spring performs SHM for

a) Only small oscillations of spring

b) Only for large oscillations of spring

c) Both large as well as small oscillations of spring

3) Give expression for restoring force in spring while performing small SHM oscillations.

4) Explain damped oscillations

5) Explain oscillations due to spring

Answer key-2

3) At any time t, if the displacement of the block from its mean position is x, the restoring force F acting on the block is,

The constant of proportionality, k, is called the spring constant, its value is governed by the elastic properties of the spring

4) In the motion of a simple pendulum, swinging in air amplitude became zero after some time. This is because the air drag and the friction oppose the motion of the pendulum and dissipate its energy gradually. The pendulum is said to execute damped oscillations. In damped oscillations, the energy of the system is dissipated continuously. The damping force is generally proportional to velocity of the bob and acts opposite to the direction of velocity. If the damping force is denoted by F d , we have F d = –b v. Where the positive constant b depends on characteristics of the medium and the size and shape of the block.

5) the small oscillations of a block of mass m fixed to a spring, which in turn is fixed to a rigid wall. The block is placed on a frictionless horizontal surface. If the block is pulled on one side and is released, it then executes to and fro motion about the mean position. Let x = 0, indicate the position of the centre of the block when the spring is in equilibrium. We know that springs have special property that when deformed is subject to a restoring force, the magnitude of which is proportional to the deformation or the displacement and acts in opposite direction. It holds good for displacements small in comparison to the length of the spring. At any time t, if the displacement of the block from its mean position is x, the restoring force F acting on the block is,

Case Study – 3

When a system (such as a simple pendulum or a block attached to a spring) is displaced from its equilibrium position and released, it oscillates with its natural frequency ω, and the oscillations are called free oscillations. All free oscillations eventually die out because of the ever present damping forces. However, an external agency can maintain these oscillations. These are called forced or driven oscillations. We consider the case when the external force is itself periodic, with a frequency w d called the driven frequency. The most important fact of forced periodic oscillations is that the system oscillates not with its natural frequency ω, but at the frequency ω d of the external agency; the free oscillations die out due to damping. The most familiar example of forced oscillation is when a child in a garden swing periodically presses his feet against the ground (or someone else periodically gives the child a push) to maintain the oscillations. The maximum possible amplitude for a given driving frequency is governed by the driving frequency and the damping, and is never infinity. The phenomenon of increase in amplitude when the driving force is close to the natural frequency of the oscillator is called resonance . In our daily life, we encounter phenomena which involve resonance. Your experience with swings is a good example of resonance. You might have realized that the skill in swinging to greater heights lies in the synchronization of the rhythm of pushing against the ground with the natural frequency of the swing.
