Question

What is Sublimation ?
​

Answer 1

Answer:

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.

Answer 2

Answer:

Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.
