Question

Quizplus · Accepted Answer

Sublimation is the process by which a solid changes directly into a gas without passing through the liquid phase. Therefore, choice C is the best answer. Choice A describes the process of melting and evaporation, which is not sublimation. Choice B describes the process of snow and ice formation, which is also not sublimation. Choice D describes the phenomenon of blue ice, which is not directly related to sublimation. Choice E describes the process of crystal growth, which is also not sublimation.
