A. Fusion: Fusion is when a solid is heated until it turns into a liquid by breaking its intermolecular forces.
B. Vaporization: Vaporization is when a liquid changes into a gas by applying heat.
C. Condensation: Condensation is the process where a gas turns into a liquid, the reverse of vaporization.
D. Solidification: Solidification is when a liquid turns into a solid, the reverse of fusion.
E. Sublimation: Sublimation is when a solid turns directly into a gas without becoming a liquid first.
F. Deposition: Deposition is when a gas turns directly into a solid without becoming a liquid first.
