Question

Appliances based on the concept of the latent heat of vaporisation

Answer 1

Answer:

Latent heat of vaporization is a physical property of a substance.When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization.

Latent heat can be understood as heat energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature.

Black used the term in the context of calorimetry where a heat transfer caused a volume change in a body while its temperature was constant.
