problem solving in gas laws

PROBLEM \(\PageIndex{3}\) One way to state Boyle's law is "All other things being equal, the pressure of a gas is inversely proportional to its volume." (a) What is the meaning of the term "inversely proportional?" (b) What are the "other things" that must be equal? Answer a . The pressure of the gas increases as the volume ...

Transcript. The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume). No gas is truly ideal, but the ideal gas law does provide a good approximation of real gas behavior under many conditions.

Problem #8: The pressure of a gas is reduced to 75% of its initial value and the volume is increased by 40% of its initial value. Find the final temperature, given that the initial temperature was −10 °C. Solution: Let us assign P 1 = 1, therefore P 2 = 0.75 Let us assign V 1 = 1, therefore V 2 = 1.4 . I won't bother with units on P or V.

However, we know something not in the problem: at sea level, the boiling point of water is 100 °C. So: 1) Let us use a ratio and proportion to estimate the pressure required for water to boil at 88 °C: 100 °C is to 101.3 kPa as 88 °C is to x x = 89.144 kPa. 2) Now, we can solve the problem using Boyle's Law: P 1 V 1 = P 2 V 2
