Latentheat
Latent heat is the energy absorbed or released by a substance during a phase transition at a constant temperature. It describes the hidden energy involved in changing the structure of a material, rather than raising its temperature. During melting, boiling, or sublimation, heat is transferred without a change in the substance’s temperature until the phase change completes.
The main types are latent heat of fusion, latent heat of vaporization, and latent heat of sublimation.
Phase changes occur at specific temperatures—the melting point for fusion and the boiling point for vaporization—and
Latent heat is central to many natural and engineered processes. Ice melting absorbs heat, water boiling requires
