Latent heat is the extra heat required to change the condition of a substance from solid to fluid at its softening point, or from fluid to gas at its breaking point after the temperature of the substance has come to both of these focuses.
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, like melting or condensation.
Jun 4, 2024 · latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.

Heat absorbed or released as the result of a phase change is called latent heat. There is no temperature change during a phase change, thus there is no change in the kinetic energy of the particles in the material.
Because this energy enters or leaves a system during a phase change without causing a temperature change in the system, it is known as latent heat (latent means hidden). The three phases of matter that you frequently encounter are solid, liquid and gas (see Figure 11.8 ).
Latent heat of a substance is the amount of energy absorbed or released by the substance during a change in its physical state that occurs without changing its temperature. SI unit of latent heat is the joule ( ).
Jul 11, 2021 · Latent heat is measured in units of J/kg. Both \(L_f\) and \(L_v\) depend on the substance, particularly on the strength of its molecular forces as noted earlier. \(L_f\) and \(L_v\) are collectively called latent heat coefficients.
Latent heat is an intensive property measured in units of J/kg. Both L f and L v depend on the substance, particularly on the strength of its molecular forces as noted earlier. L f and L v are collectively called latent heat coefficients.
Latent heat is the energy (see note below) released or absorbed during a phase change, where the temperature does not change. This is because all of the heat is used up in the phase change, rather than into changing temperature. For a more in-depth explanation specifically of latent heat of fusion, see the link.
