What is sublimation?
Sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase. ... The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.
When anything solid turns into a gas without first becoming liquid, that's sublimation. When the surface layer of snow or ice turns into fog or steam without melting, this is an example of sublimation. The noun sublimation is from the Latin word sublimare, meaning ?to raise a higher status.?
