Problem

Which statement is inconsistent with the kinetic theory of an ideal gas?

Most of the volume occupied by a gas is empty space.

The forces of repulsion between gas molecules are very weak or negligible.

Gas molecules move in a straight line between collisions.

The average kinetic energy of a gas is proportional to the absolute temperature.

The collisions between gas molecules are inelastic.

Solution

We are asked which of the following is inconsistent with the kinetic theory of an ideal gas?

A gas is seen as a collection of molecules or individual atoms that are in constant motion. 

The Kinetic-Molecular Theory tries to use data of real gases to predict how an ideal gas would behave if they existed.

Ideal gases are imaginary and don’t actually exist. However, if they did exist then there would be certain characteristics that a gas would need to possess in order to be an ideal gas.
