# Latent Heat

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Latent heat is the energy absorbed or released by a substance during a constant temperature or phase change from a solid to liquid, liquid to gas or vise versa.

## 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:

$$Q = mL$$
