## Heat of Vaporization Formula

The following equation is used to calculate the heat of vaporization.

Hv = q / m

- Where H
_{v}is the heat of vaporization (J/g) - q is the total heat of the liquid at the vaporization point. (J)
- m is the total mass of the liquid (g)

To calculate a heat of vaporization, divide the total heat of the liquid at the vaporization point by the mass of the liquid.

## Heat of Vaporization Definition

The heat of vaporization is a measure of the amount of energy it takes to vaporize a liquid.

## Heat of Vaporization Example

How to calculate heat of vaporization?

**First, determine the mass of the liquid.**Measure the total mass of the liquid being vaporized.

**Next, determine the total heat.**Add heat to the liquid until the liquid starts to vaporize. Measure the total heat at this point.

**Finally, calculate heat of vaporization.**Divide the total heat by the total mass to determine the heat of vaporization.
