# Latent Heat

Written by Jerry Ratzlaff. Posted in Thermodynamics

Latent heat is the heat required to change a material without a change in temperature.

## formula

$$L = \frac{Q}{m}$$

Where:

$$L$$  = latent heat of a substance

$$Q$$ = amount of energy transferred for the phase change

$$m$$ = mass of the substance

Solve for:

$$Q = mL$$
