Question

what is sublimation ​

Answer 1

Answer:

Sublimation is the process by which solid water is directly transformed into vapour water. ... While sublimation can occur at atmospheric pressure, the process is rather slow because the gas molecules from the ice must find their way through the atmospheric gases that are bombarding the surface of the ice.
