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

\( latent \; heat  \;=\;  \frac { energy \; transfered } { mass \;  of \; the \; substance }\)

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


\(L \)  = latent heat of a substance

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

\(m\) = mass of the substance

Solve for:

\(Q = mL\)
