It depends on the liquid you've got. But it's called the Latent Heat of Vapourisation

The energy needed to change a liquid to a gas is called the heat of vaporization. This energy is required to overcome the intermolecular forces holding the liquid molecules together and allow them to escape into the gas phase. The heat of vaporization is specific to each substance and is typically higher than the heat needed to raise the temperature of the substance from solid to liquid or from liquid to gas.

What is the heat energy needed to change a liquid to gas while the temperature stays the same?
The heat energy needed to change a liquid to gas while the temperature stays the same is called the heat of vaporization. This energy is used to overcome the intermolecular forces holding the liquid molecules together and convert them into a gas. It is a phase change process that occurs at the boiling point of the substance.
What is the energy required to go from liquid to gas called?
The latent heat of vaporization
When energy is added to a liquid and it changes into a gas it is called?
When energy is added to a liquid causing it to change into a gas, it is called vaporization or evaporation. This process involves the liquid molecules gaining enough energy to break free from the attractions holding them together in the liquid phase and transition into the gaseous phase.
What information does latent heat of vaporization give?
The latent heat of vaporization indicates the amount of heat energy required to change one unit of mass of a substance from liquid to gas at constant temperature. It is a measure of the strength of the intermolecular forces holding the liquid together.
Change from liquid to a gas?
The change from liquid to a gas is called vaporization or evaporation. This process occurs when a liquid's molecules gain enough energy to overcome the attractions holding them together in the liquid state, allowing them to move freely as a gas.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called heat of vaporization.
What energy needed to change 1 kg of liquid into gas at boiling point?
Thermal Energy
What type of heat energy is needed to change a material from a liquid to a gas?
endothermic
What is the engery required to go from liquid to gas called?
The energy required to go from liquid to gas is called heat of vaporization. This is the amount of energy needed to change a substance from a liquid into a gas at constant temperature and pressure.
What energy is needed to change a material from a liquid to a gas?
Usually heat is needed. but this can happen through osmosis as well.
What is the process by which radiant energy from the sun causes a liquid to change into gas?
The process by which radiant energy from the sun causes a liquid to change into a gas is called evaporation. When sunlight shines on a liquid, it provides the energy needed to break the bonds holding the liquid molecules together, allowing them to escape into the air as gas.
What form of energy is needed to cause substances to change form one solid to a liquid and a liquid to a gas?
thermal energy is needed to do that job. as opposed to mechanical potential or chemical energies.
What is the heat energy needed to change a liquid to gas while the temperature stays the same?
The heat energy needed to change a liquid to gas while the temperature stays the same is called the heat of vaporization. This energy is used to overcome the intermolecular forces holding the liquid molecules together and convert them into a gas. It is a phase change process that occurs at the boiling point of the substance.
During which three changes of state is energy absorbed?
cchemical change and energy change also the change of a gas to a liquid
What does the latent heat of vaporization represent?
The amount of energy required to turn a mole of a liquid into a gas
What is the energy required to go from liquid to gas called?
The latent heat of vaporization
What is needed for a liquid to change to a gas?
Heat
