The process by which molecules escape from a solid directly into the gas phase is called
A) gasification
B) evaporation
C) condensation
D) sublimation

Question

Quizplus · Accepted Answer

Sublimation is the process by which molecules escape from a solid directly into the gas phase, without passing through the liquid phase. This typically occurs at temperatures and pressures below the substance's triple point. Evaporation is a similar process, but refers specifically to the transformation of a liquid into a gas, whereas sublimation refers to the transformation of a solid into a gas. Gasification refers more broadly to the conversion of a substance into a gas, and can encompass both evaporation and sublimation. Condensation, on the other hand, refers to the transformation of a gas into a liquid or solid, and is the opposite of evaporation and sublimation.
