When does submiliation happen?

Answer 1

Sublimation occurs when a substance transitions directly from a solid state to a gas state without passing through the liquid phase. This process typically happens at specific temperatures and pressures, often under low-pressure conditions, and is most commonly observed in substances like dry ice (solid carbon dioxide) and certain types of ice. Sublimation can also occur in various natural processes, such as the sublimation of snow or ice in cold, dry conditions.
