A group of scientists from the Technical University of Madrid has fabricated a latent heat thermophotovoltaic (LHTPV) battery that is able to store electricity in the form of latent heat at ...

Specific latent heat is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature. As there are two boundaries, solid/liquid and liquid ...

The relationship used to determine the heat energy required to change the state of a substance is: \(E_{h} = ml\) \(E_{h}\) is the energy required to change the state ( \(J\)) \(l\) is the ...

Unlike the conventional cooling method, which uses a temperature difference to transfer heat from a heat source to a refrigerant (water or air), the latent heat of evaporation (vaporization heat) ...
