Sublimation is the process of going directly from a solid to a gas. Dry ice bypasses changing into a liquid state before converting to gas. That is why it is called ”dry“ ice. ... Eventually, water ice will form a covering onthe dry ice and then crack or pop, as thepressure of carbon dioxide gas further builds up inside

Sublimation is the process in which solid turns into gaseous state directly.
