The temperature of a gas depends on

• the average kinetic energy of the gas particles.

• the pressure of the gas particles.

• the mass of the gas particles.

Which of the following is not true about the volume of a gas?

• Most of the volume is empty space.

• The volume is occupied by particles in continuous, rapid, random motion.

• The volume is about 10 times greater than that occupied by an equal number of particles in the liquid or solid state.

• Generally, the volume can be easily changed.
