The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
endothermic
Usually heat is needed. but this can happen through osmosis as well.
The change from a liquid to a gas is evaporation.
Thermal Energy
* To change a gas into a liquid you need to evaporate the gas by heating it
The change of a liquid to a gas is Vaporization. Not to be confused with "Evaporation".
A change of state from a gas to a liquid is called condensation.
No, a liquid changing to a gas is a change of state or a physical change.
No, a liquid changing to a gas is a change of state or a physical change.
A liquid can change to a gas, by heating up and evaporating into the air.
thermal energy is needed to do that job. as opposed to mechanical potential or chemical energies.
