Answer:

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#
