Direct change of gas to solid without changing in to liquid is called ___________.

Correct option is B

The correct answer is (b) Deposition.
· Deposition is the process where a gas changes directly into a solid without first becoming a liquid.
· This is the reverse process of sublimation, where a solid changes directly into a gas.
· An example of deposition is the formation of frost, where water vapor in the air directly turns into ice without becoming liquid first.

Vaporization:
· The process of a liquid changing into a gas, typically through boiling or evaporation.
Evaporation:
· A type of vaporization that occurs at the surface of a liquid as it turns into a gas below its boiling point.
Sublimation:
· The process where a solid changes directly into a gas without becoming a liquid, such as dry ice turning into carbon dioxide gas.
