Question

what is standard enthalpy of vaporisation ??​

Answer 1

HeY Mate!!

The enthalpy of vaporization, also known as the heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance, to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. 

I hope it's help for you!

Answer 2

HELLO !! ☺☺☺

ENTHALPY OF VAPORISATION :

Amount of heat required to vapourise one mole of a liquid at constant temperature and under standard pressure (1bar )is called it's standard enthalpy of vaporisation .
