The SI unit of latent heat is Joule.
The concept of latent heat was first introduced by a British chemist Joseph Black.
Latent heat is defined as the heat required for converting solid into a liquid or to vapour without any change in the temperature.
Examples of latent heat:
- Cooling through perspiration is an example of latent heat.
- Intensifying of hurricanes is an example of latent heat. Latent heat is released when the warm water turns into water vapour because of hot air. When the air gets heated there will be an instability in the clouds resulting in intensifying of the storm.
