Is sublimation melting or freezing

Answer 1

SUBLIMATION: It is a process in which a solid instead of changing into liquid state changes directly into gaseous state upon heating. MELTING: It is a process in which a solid at its melting point changes into liquid state upon heating.

Answer 2

Melting is the process of a solid going through a physical change to the liquid state.

Sublimation is the process of a solid going immediately to the gaseous state, skipping the liquid state entirely. You can seesublimation in action by seeing a block of dry ice (frozen carbon dioxide gas) "melt" from a solid into white smoke.

Answer 3

Neither. Melting is the process of a solid becoming a liquid. Freezing is the process of a liquid becoming a solid. Sublimation is the process of a solid becoming a gas.

Answer 4

Melting is when a solid changes phase to a liquid.

Sublimation is when a solid changes phase directly to a vapour without going through the liquid phase.

Answer 5

Sublimation is the process in which a substance transitions directly from the solid phase to the gas phase without passing through the liquid phase. It does not involve melting or freezing.
