Latent Heat

Latent Heat

Latent heat ( \(L\) ) 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.

Latent Heat Formula

\(\large{ L = \frac{Q}{m}  }\)         

Where:

\(\large{ L }\)  = latent heat of a substance

\(\large{ m }\) = mass of the substance

\(\large{ Q }\) = amount of energy transferred for the phase change

Solve for:

\(\large{ Q = mL }\)
