Chapter 6, Problem 6.46QP

Interpretation Introduction

Interpretation: The reduction in the rate of ascent brought about by the pilot by allowing some gas to leak out of the balloon is to be validated.

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.
• Low or high pressure depends upon number of gas molecules that collide with each other. It means pressure is directly related to number of molecules.
• The average kinetic energy of every gas particles is directly related to temperature. The speed of gas molecules increases with increase in temperature.

To validate: The reduction in the rate of ascent brought about by the pilot by allowing some gas to leak out of the balloon.
