Sublimation is the process where a solid changes directly into a gas instead of changing into a liquid then a gas. A popular example of this process is the transition of dry ice (carbon dioxide) readily turning directly into CO2 gas in standard conditions.
It's called sublimation. An example is dry ice, or solid Carbon dioxide. When heated, CO2 changes directly from the solid state to the gaseous state.
condensation, reversed sublimation
Solids changing to liquids are melting Liquids changing to solids are freezing Solids changing to gas are subliming Liquids changing to gas are boiling Gases changing to liquids are condensing.
A liquid evaporating is a physical change. Anything changing from a solid to a liquid (or liquid to solid), or from a liquid to gas (or gas to liquid) is a physical change).-Alec Vasquez
Dry ice is the solid form (state of matter) of carbon dioxide (CO2).Under normal circumstances, it will change state from a solid directly to a gas. It does this without melting (changing state to a liquid). We call the direct transformation of a solid to a gas sublimation, and dry ice is said to sublime when going directly from its solid state to a gas.
It depends!!When you turn water from liquid to solid, it doesn't requires heat.It is so called SOLIDIFICATION.Then if liquid to gas,the liquid requires more heat inorder for it to become a water vapor...The process is called EVAPORATION..™J-Neil™
Platinum is a solid.
The changing of gas into solid is sublimation. it is the opposite of evaporation the changing of solid into gas.
Changing directly from a gas to a solid is called deposition.Changing directly from a solid to a gas is called sublimation.
A solid changing to a gas without becoming a liquid first is called sublimation.
When solid is heated and melt then it will change into gas
Sublimation
Deposition is when a gas changes directly into a solid.
Changing from a solid to a liquid is a physical change as is changing from a liquid to a gas.
Examples of a gas changing directly into a solid (deposition) - Water vapor in a cloud changing into solid snowflakes. Water vapor in the air turning directly to frost on any sub-freezing surfaces.

Ironisation is the process of changing gas into plasma. Other processes of changing state include: Solid -> liquid = melting Liquid -> gas = condensation Gas -> liquid = evaporation Liquid -> solid = freezing Solid <- -> Gas = sublimation
