According to the kinetic-molecular theory, which of the following best explains why gases can be compressed much more easily than liquids or solids?
The distance between gas particles is very large compared to the size of the particles themselves.
Gas particles can be squashed and reduced in individual volume.
Gas particles lose kinetic energy when they collide.
The forces of attraction between gas particles are extremely strong.
