Question

what is sublimation​

Answer 1

ⒽⓁⓄ

Sublimation is a type of phase transition, or a change in a state of matter, just like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid CO2, provides a common example of sublimation.

Answer 2

Answer:

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.
