Question

Quizplus · Accepted Answer

Sublimation is the direct conversion of solid to gas (vapor) without going through the liquid state. Therefore, ice changing directly into water vapor is an example of sublimation. Choices A, B, and D describe other processes such as melting and changes in color and density, which are not related to sublimation.
