Question

What is sublimation?!​

Answer 1

Answer:

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 process by which solid water is directly transformed into vapour water. When sublimation occurs during the freeze-drying step, it is commonly referred to as the “primary drying process”.
