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.
an example of a gas to solid is dry ice
Sublimation
sublimation. for example when dry ice changes directly to a gas.
Sublimation which transforms a solid directly to a gas.
The phase change from gas to solid is called deposition.For example, at 5 times normal air pressure, liquid carbon dioxide would form around -56°C (-70 °F). But at normal pressure, the liquid is unstable and tends to remain a gas. Cooling the gas further to -78.5 °C (-109.3 °F) will form solid dry ice.
Gas -> liquid = condinsation Liquid -> solid = solidification Solid -> liquid = fusion Liquid -> gas = evaporation Solid directly to gas (with out becoming liquid) = sublimation Example = dry ice at room temperature.
Changing directly from a gas to a solid is called deposition.Changing directly from a solid to a gas is called sublimation.

Deposition is when a gas changes directly into a solid.
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.

Sublimation
This is called sublimation- an example is when solid carbon dioxide *dry ice* bypasses the liquid state and directly becomes a gas

The process of changing a solid directly to a gas skipping the liquid stage is called sublimation.
