# Heat of Vaporization

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Heat of vaporization, abbreviated as $$H_v$$, is the amount of heat needed to be consumed to vaporize a specific amount of liquid at a constant temperature.

## Heat of vaporization Formula

 $$\large{ H_v = \frac{ q }{ m } }$$

### Where:

$$\large{ H_v }$$ = heat of vaporization

$$\large{ q }$$ = heat

$$\large{ m }$$ = mass of substance
