If something changes directly from a solid to a gas, it is said to sublime. This happens at time with ice, for example, were, instead of melting to a liquid it converts directly to water vapor.
interconversion between solid to liquid to gas is physical change
Physical
The change of state directly from solid to gas is called sublimation, and the change from gas to solid is called deposition.
When solid is heated and melt then it will change into gas
When something changes between solid, liquid, gas, or plasma
The PHASE change of solid TO gas is called Sublimation.
The change between a gas and a solid is called deposition. This process occurs when gas particles lose energy and transition directly into a solid state without passing through the liquid phase. An example of deposition is the formation of frost when water vapor in the air turns directly into ice on cold surfaces.
Sublimation is a change of state directly from a Solid to a Gas, or a Gas to a solid. There is no intermdiate liquid stage. Carbon dioxide ( gas) sublimes to Dry Ice (Solid Carbon dioxide).
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.
