What is specific latent heat?
Feb 3, 2017
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.
There are two types:
- Latent heat of fusion (
#L_f#): the amount of thermal energy required to melt or freeze 1kg of a substance.
- Latent heat of vaporization (
#L_v#): the amount of thermal energy required to evaporate or condense 1kg of a substance.
To calculate latent heat:
