There are probably several ways to build a heat pump; for example, a substance might be compressed and expanded. If latent heat is used, this is probably because it is easier and more efficient to build the heat pump that way.
The amount of energy required to turn a mole of a liquid into a gas
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
latent heat of fusion tells us about the amount of energy that must be taken off from water at 00C to fuse it into ice at 00C . Actually this in this phase temperature remains constant and this energy is (either latent heat of fusion or latent heat of vaporization is the potential energy which is possessed by the states by their virtue.
No. Latent heat of vaporization is defined as the energy required to VAPORIZE 1 kilogram of a liquid completely at its boiling point. Latent heat of sublimation is the energy required to SUBLIME 1 kilogram of a solid completely into a gas at constant temperature. They're different. Note that the temperatures should be constant during the processes.
Latent heat of vaporization.
The latent heat of evaporation
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
Refrigerator, freezer and air conditioner.
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.
