C. its particles move farther apart and the substance becomes a gas.
D. its particles move closer together and the substance becomes a solid.

C. its particles move farther apart and the substance becomes a gas.

Explanation:

A. is wrong because moving closer together creates a solid, not a gas.

B. is wrong because moving father apart creates a gas, not solid.

C. is correct because moving farther apart creates a gas.
