Question

what is sublimation​

Answer 1

Answer:

When anything solid turns into a gas without first becoming liquid, that's sublimation. When the surface layer of snow or ice turns into fog or steam without melting, this is an example of sublimation.

Answer 2

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.

Example:

Dry ice, solid CO2, provides a common example of sublimation.

Snow and ice can sublime in the winter months without melting.

Moth balls sublime.
