Chapter 19, Problem 123A

Interpretation Introduction

Interpretation : The law that describes an inverse relationship is to be identified.

Concept Introduction : According to kinetic theory, a gas's particles are separated from one another by empty space.

Answer to Problem 123A

Charles’s law does not give the inverse relationship in gas particles.

Explanation of Solution

According to Charles' law, a gas's volume and Kelvin’s temperature are both directly proportional.

If the pressure remains constant, the volume of a confined gas rises as the temperature does.

Charles’s law gives the direct relationship between volume and temperature.

Answer to Problem 123A

Boyle’s law describes an inverse relationship between pressure and volume.

Explanation of Solution

Boyle's law asserts that the volume of a gas changes inversely with pressure for a given amount of gas at a fixed temperature.

If the temperature remains constant, a gas's volume drops as its pressure rises.

Boyle’s law gives the inverse relationship between volume and pressure.

Answer to Problem 123A

Gay-Lussac’s law does not give the inverse relationship in gas particles.

Explanation of Solution

According to Gay-Lussac's law, assuming the volume stays constant, the pressure of a gas is precisely proportional to the Kelvin temperature.

If the volume remains constant, the pressure rises as the temperature of a gas confined increases.

Gay-Lussac’s law gives the direct relationship between pressure and temperature.
