Which is not true in case of an ideal gas?

Options

A. It cannot be converted into a liquid
B. There is no interaction between the molecules
C. All molecules of the gas move with same speed
D. At a given temperature, pV is proportional to the amount of the gas

Answer

C

Explanation

A gas is a collection of tiny particles separated from one another by large empty space and moving rapidly at random in all the directions. In the course of their motion, they collide with one another and also with the walls of the container. Due to frequent collisions, speeds and direction of motion of molecules keeps on changing. Thus, all the molecules in a sample of a gas do not have same speeds.
