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.

2025年1月16日 · Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance undergoing a change of state.

Latent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance. It could either be from a gas to a liquid or liquid to a solid and vice versa. Latent heat is related to a heat property called enthalpy.

2019年11月4日 · Get the definition of latent heat and a table of values. Learn the difference between heat of vaporization, latent heat of fusion, and sensible heat.

2024年7月6日 · Latent heat is the heat required to transform a solid into a liquid or vapour phase. It is known by several names depending on its phase, such as the heat of condensation, the heat of vaporization, and so on.

The specific latent heat of a substance is the amount of energy needed to change the state of 1 kg of the substance without changing its temperature. Each substance...

Latent heat is the heat required for an object to change phase (melt, boil, freeze, etc.). This energy is closely related to enthalpy . [1] In figure 1, very cold ice has heat added to it.
