Does melting absorb or release latent heat
Latent 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 its temperature… WebSpecific latent heat is characterized as the measure of heat energy (heat, Q) that is consumed or discharged when a body experiences a steady temperature process. The formula for specific latent heat is: L = Q/m. …
