A gas become a liquid after cooling to the adequate temperature - the condensation point.
If a liquid was to boil to change state, it would be changing from a liquid to a gas, and would be said to be boiling.
sublimate
In order for a liquid to become a gas, the particles in the liquid have to heat up enough to separate and further themselves out from each other. Bobette la Baleine : That's what I said in a shorter way.
I'm going to assume your question is asking for what said transition is called. The phase change of a liquid to a gas is vaporization. Vaporization can be broken down into evaporation and boiling.
Solid
evaporation solid to liquid - melting liquid to gas - evaporation gas to liquid - condensation liquid to solid - freezing solid to gas and gas to solid - sublimation
The process from a liquid to a gas is called evaporation, where the liquid absorbs heat energy and changes into a gas. On the other hand, the process from a gas to a liquid is called condensation, where the gas loses heat energy and changes into a liquid. Both processes involve a change in temperature or pressure.
evaporation solid to liquid - melting liquid to gas - evaporation gas to liquid - condensation liquid to solid - freezing solid to gas and gas to solid - sublimation
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas. It is a characteristic property of the liquid and can be influenced by factors such as pressure and impurities in the liquid.
Water vapour is not completely a gas.It contains a lot of water.But it can also be said as a gas........
Is a pencil a solid liquid or gas
A liquid or solid (not a liquid gas)
