ANSWER

The process of a solid changing to a gas is called SUBLIMATION

The process of solid turning to liquid is called MELTING

Step-by-step explanation:

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

This occurs when the particle of the solid acquires enough energy to completely overcome the force of attraction holding the solid particles together.

Example: dry ice in water changing directly to carbon dioxide gas

Therefore, the process of a solid changing to a gas is called SUBLIMATION

The process of solid turning to liquid is called MELTING
