The heat of deposition equals the negative of the heat of sublimation.

Question

Quizplus · Accepted Answer

This statement is true. The heat of deposition is the amount of energy released when a substance goes directly from a gas to a solid. The heat of sublimation, on the other hand, is the amount of energy required to change a substance from a solid directly to a gas. Since deposition is the reverse process of sublimation, the two processes have equal but opposite heats.

The Heat of Deposition Equals the Negative of the Heat
