Chapter 14, Problem 48A

Interpretation Introduction

Interpretation: To determine why heating a contained gas that is held at a constant volume increases its pressure.

Concept Introduction: A theoretical gas called an ideal gas is made up of several independently moving point particles without any interparticle interactions. Because it adheres to the ideal gas rule, the ideal gas concept is helpful.

Answer to Problem 48A

Because collisions take place more frequently and violently because of the particles' higher kinetic energy.

Explanation of Solution

Gay Lussac's Law states that when a gas is maintained at a fixed volume, its pressure will be exactly proportional to its Kelvin temperature. A gas's molecules move more swiftly when it is heated because they are given more energy. The increased pressure and more impacts on the container's walls are the outcomes of this.

It can be argued that collisions occur more frequently and violently due to the particles' higher kinetic energy.
