Answer:
Explanation:
A substance may undergo phase change from a solid to a gas or from a gas to a solid if the temperature it is exposed to is changed very quickly. If the temperature around a solid is raised very quickly, it can sublimate, or phase change from a solid to a gas without existing as a liquid. In the opposite direction, a gas that is suddenly supercooled can undergo complete deposition.
