What is the energy required to go from liquid to gas called answers?

The energy required to go from liquid to gas is called as Latent Heat of Vaporization.

Explanation:

The process of conversion of liquid into gas phase is known as vaporization while the conversion of gas into liquid state is called as condensation. The liquid having stronger intermolecular forces than gases require some energy to break those interactions hence, the heat provided to break these interactions and convert it into gas phase is called as heat of vaporization. Remember, heat of vaporization and heat of condensation are same for a given substance but with different signs.

Example:

Heat of Vaporization of Water = 40.65 kJ/mol

Heat of Condensation of Water = - 40.65 Kj/mol
