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

What is the heat energy needed to change a liquid to gas while the temperature stays the same?
(latent) heat of vaporization
When energy is added to a liquid and it changes into a gas it is called?
When enough energy is added to a liquid for it to change to a gas, the liquid has reached its _______________
How does water changes to solid liquid and gas?
Changing phase (solid, liquid, gas) requires energy. Adding energy allows the molecules to move apart and solid change to liquid or liquids change to gases.
What information does latent heat of vaporization give?
The amount of energy required to turn a more of a liquid into a gas - apex
Change from liquid to a gas?
The process of a liquid turning into gas is called evaporation. This is when the particles in the liquid gain heat energy and diffuse off as a gas form.
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 the enthalpy (or 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 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 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.
During which three changes of state is energy absorbed?
cchemical change and energy change also the change of a gas to a liquid
What energy required to go from liquid to gas?
No. Energy is require to change it from liquid to gas. When water goes from gas to liquid it releases energy.
What change release energy?
Gas to liquid change releases energy.
What is the heat energy needed to change a liquid to gas while the temperature stays the same?
(latent) heat of vaporization
What is needed for a liquid to change to a gas?
Heat
Which of the changes of state shown in the figure require an increase in energy answers?
Evaporation uses energy to change from a liquid to a gas. Melting uses energy to change from a solid to a liquid. Condensation releases energy to change from a gas to a liquid. Freezing releases energy to change from a liquid to a solid.
When energy is added to liquid what does it change into?
The liquid is changed in a gas.
