Question

define specific latent heat of fussion
​

Answer 1

Answer:

The latent heat of fusion refers to the phase change between states of solid and liquid. Here, heat actually refers to the transfer of heat energy between the objects. Thus, the latent heat of fusion encompasses the process of adding heat to melt some solid.

Latent heat of fusion, also known as enthalpy of fusion, is the amount of energy that must be supplied to a solid substance (typically in the form of heat) in order to trigger a change in its physical state and convert it into a liquid (when the pressure of the environment is kept constant).

There is flexibility in the choice of phase-change temperature range and latent heat of fusion. The recommended phase-change temperature range is from 25 [degrees]C to 27 [degrees]C (77 [degrees]F to 80.6 [degrees]F) and the latent heat of fusion is 23,0132 J/kg (98.9 Btu/lb).
