*The amount of heat required to convert one mole of a liquid into vapour is known as​

Answer 1

Answer: Latent heat of vaporisation

Answer 2

Answer : enthalpy of vaporization

explanation : enthalpy of vaporization is also known as enthalpy of evaporation (because a liquid converts into vapour in this process). it is the amount of energy that must be added to a liquid substance to convert into a vapour.

i.e., P (l)  + Q( heat )  ⇄ P (g)

here Q is heat required to change the phase of liquid P into vapor , so Q is enthalpy of vaporization.

 Therefore the amount of heat required to convert one mole of a liquid into vapour is known as enthalpy of vaporization.
