For a solid to change into a gas, the conditions needed are high enough heat and low enough air pressure.
When solid is heated and melt then it will change into gas
Solid to Gas phase change is called Sublimation
The PHASE change of solid TO gas is called Sublimation.
Sublimation is an endothermic physical change (heat is needed).
The solid -> gas transition is called sublimation. The gas -> solid transition is called deposition.
When solid is heated and melt then it will change into gas
a phase change: solid to liquid: melting liquid to solid: freezing liquid to gas: vaporization gas to liquid: condensation solid to gas: sublimation gas to solid: deposition
Please note that a "change of state" involves TWO states, not just one. Using just the three most common states of matter: * A solid can change to a gas * A liquid can change to a gas * A gas can change to a liquid * A gas can change to a solid * A solid can change to a liquid * A liquid can change to a solid The first four changes in the list above involve gases.

evaporation is the change from a liquid to a gas
Yes, sublimation is a change from solid to gas.
A phase change directly from a gas to a solid is called deposition.
