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
