Answer to Question #225439 in Physics for Div

Question

I need formula for finding specific latent heat

Answer 1

The specific latent heat $L$ can be found from the equation:

$$Q = Lm$$

where $Q$ is the amount of heat required to completely effect a phase change (vaporization/сondensation or melting/crystallisation) of a substance of mass $m$.

Thus:

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