The question is incomplete. The complete question is
Absorption of energy into the refrigerant causes a phase change from _____.
solid to liquid
liquid to vapor
vapor to liquid
liquid to solid
Answer:
liquid to vapor
Explanation:
According to the kinetic theory of matter, matter in the gaseous state contains more energetic particles than matter in the liquid state.
Hence if a refrigerant in the liquid state absorbs sufficient energy, it undergoes a phase change from liquid to vapour. Hence the answer.
