It is a measurement of the amount of heat energy (Q) emitted or absorbed per mass (m) during a phase shift. The formula Q = mL is used to describe it. It's commonly referred to as the material's "latent heat."
Latent heat can be understood as hidden energy which is supplied or extracted to change the state of a substance without changing its temperature or pressure. Enthalpy of sublimation · Enthalpy of vaporization · Enthalpy of fusion |

Скры́тая теплота́ — теплота, высвобождаемая или поглощаемая термодинамической системой при изменении своего состояния, но не сопровождаемая изменением температуры. Наблюдается при фазовых переходах: плавлении, парообразовании, отвердевании и т. д.... Википедия
The specific latent heat of water is: l f = 3 ⋅ 34 × 10 5 J k g − 1 for fusion (solid→liquid) or freezing (liquid→solid) l v = 22 ⋅ 64 × 10 5 J k g − 1 ... |
When a material changes phase, it absorbs or releases latent heat. It does this without changing temperature. The equation that describes this is Q = mL. |
... formula is: Specific latent heat = (Heat energy) / (mass of substance). →What are some common substances with high specific latent heat values? Water ... |
The latent heat formula is as follows: L = Q/M where, L = a substance's specific latent heat, Q = quantity of heat, M = the substance's mass. |
The equation for the specific latent heat of fusion and the specific latent heat of vaporization is identical: E = L m . We use the specific latent heat of ... |
