Chapter SM, Problem 13PQ

Interpretation Introduction

Interpretation:

The set of temperature and pressure conditions that will cause gas to exhibit greatest deviation from ideal gas behavior has to be determined.

Concept Introduction:

Ideal gas is hypothetical or theoretical gas that is formed from large number of randomly moving particles with perfectly elastic collisions between them. This gas is considered to follow ideal gas law under all conditions.

The postulates followed by kinetic theory of gases are as follows:

1. The size of gas particles is considered to be small and is situated far apart from each other. The majority of volume of the gas is an empty space.

2. There is rapid motion of molecules of gas that occurs randomly in all directions.

3. The gas molecules undergo collisions with each other and with walls of container. The collisions between molecules and container walls are responsible for pressure of gas.

4. The collisions of gas molecules are supposed to be perfectly elastic so no loss in kinetic energy is observed.

5. Gas molecules do not interact with each other during their collisions.
