Calculating heat absorbed or released when any gas / liquid transformation takes place.
I'm not an engineer, but I would imagine these calculations are performed in designing steam plants to make electricity. Water must be boiled, the steam runs thru a steam turbine, then it is condensed into water and is recycled ... boiledto steam ... thru turbine ... condensed etc.
The latent heat of evaporation
Refrigerator, freezer and air conditioner.
coclude the specific latent heat of vaporization
The latent heat of vaporization is what is commonly referred to as boiling. This is the amount of energy require to change from a state of liquid to vapor.
The energy required to boil a substance
87.6kcal/kg
Vaporization is the change of liquid water to water vapor. Vaporization requires addition of the latent heat of vaporization to liquid water. The latent heat of vaporization supplies the liquid water molecules with enough energy to become vapor molecules. The latent heat of vaporization at 1.0 atmosphere pressure is about 1000 Btu per lbm ( 2260 kJ per kg ).
2260 kJ/kg
Perspiration coats the outside of the skin with moisture (water). The water evaporates. Evaporation requires heat to be absorbed by the water (the latent heat of vaporization). Heat is removed from the body surface to provide the water with the latent heat of vaporization.
Because the latent heat of fusion and latent heat of vaporization are very high
The amount of energy required to turn a mole of a liquid into a gas
L can either mean the latent heat of vaporization or condensation. The latent heat of vaporization is the energy required to completely turn 1 kilogram of a liquid into a gas at its boiling point. The latent heat of condensation is the energy required to completely turn 1 kilogram of a solid into a liquid at its melting point.
