Question

What is specific latent heat?

Answer 1

Specific latent heat is the amount of thermal energy absorbed or released during a phase change. Its symbol is L and its units are in J/kg.

Explanation:

There are two types:

1. Latent heat of fusion (`L_f`): the amount of thermal energy required to melt or freeze 1kg of a substance.
2. Latent heat of vaporization (`L_v`): the amount of thermal energy required to evaporate or condense 1kg of a substance.

To calculate latent heat:
`Q = Lm`
