Chapter 16, Problem 16A.1BE

Interpretation Introduction

Interpretation:

The number of collisions made by helium atoms on the surface with the dimension of $3.5\text{cm}\times 4.0\text{cm}$ in the time period of $10\text{s}$ is to be calculated.

Concept introduction:

The kinetic theory of gases is useful in finding out the expression for the diffusion characteristics of a perfect gas. Collision flux is defined as the rate of collision of the gas molecules at some region or surface. Collision flux is equal to the number of collisions divided by the time interval and the surface area of the region.
