Question: 1 / 400

What is the name of the process by which a solid changes directly to a gas?

Evaporation

Sublimation

Sublimation is the process by which a solid changes directly into a gas without first becoming a liquid. This option is correct as it accurately describes the process described in the question.

Evaporation (A) and Condensation (C) are incorrect as they refer to the process of a liquid changing into a gas and a gas changing into a liquid, respectively. These processes do not involve a solid.

Deposition (D) is incorrect as it is the opposite of sublimation - the process where a gas changes directly into a solid, bypassing the liquid stage. This is not the process described in the question.
