If particles of matter gain or lose enough kinetic energy what can happen? A. They can gain or lose electrons.
B. None of these
C. They can change phase.
D. They can gain or lose potential energy.

B

When a sample of solid, liquid, or gas matter heats up, it expands. When matter gets hot, its particles gain kinetic energy. The increased kinetic energy pushes the particles farther apart. This causes the matter to expand.
