In what unit is heat of fusion expressed
WebLatent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.. Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing … WebThe heat of fusion of any substance is the important calculation of the heat.
