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 cannot be changed easily

• Generally, the volume can be easily changed

Which of the following is an assumption of the kinetic-molecular theory of gases?

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

• The temperature of a gas depends on the average kinetic energy of the gas particles.
