Question

What is the principle of sublimation

Answer 1

Sublimation is a face transition that occurs at temperatures and pressures below, what is called the triple point of substance.

Answer 2

Sublimation is a process in which a solid turns directly into gas without passing into liquid state. The solids having very weak intermolecular forces have a higher vapour pressure than usual due to which these solids pass directly into vapour.
