Answer:
Step-by-step explanation:
This is the invisible heat required to change the state of a body either from solid to liquid or from liquid to gas.
Latent heat is not detectable by a thermometer.
There are two types of latent heat
(1) Latent heat of fusion
(2) Latent heat of vaporization
(1) Latent heat of fusion: This is the heat energy required to convert a substance from its solid form to its liquid form without a change in temperature.
(2) Latent heat of vaporization: This is the heat required to convert a substance from its liquid form to vapour without a change in temperature.
