Chapter 6, Problem 6.38QP

Interpretation Introduction

Interpretation: The helium balloon which has more collisions at room temperature between a $1\text{L}$ helium balloons at $0.1\text{atm}$ or a $1\text{L}$ helium balloon at $455\text{mmHg}$ is to be determined.

Concept introduction: According to kinetic molecular theory postulates,

• Particles present in the gas have consistent and random motion. They collide with each other or the walls of their container and these collisions are elastic in nature.
• The average kinetic energy of every gas particles is directly related to temperature. The speed of gas molecules increases with increase in temperature.
• Molecules having low molar mass will move faster than the molecules with high molar mass.
• When gas molecules collide with each other or the walls of their container, pressure is also exerted. It happens due to the velocity by which molecules collides with each other.

To determine: The helium balloon which has more collisions at room temperature.
