Latent heat - Wikipedia
网页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.
Latent heat | Definition, Examples, & Facts | Britannica
网页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.
潜热 - 百度百科
网页是指在温度保持不变的 条件 下，物质在从某一个相转变为另一个相的 相变 过程中所吸入或放出的热量。 是一 状态量。 因任何物质在仅吸入（或放出）潜热时均不致引起温度的升高（或降低），这种热量对温度变化只起潜在作用，故名。 例如，液体蒸发时从周围吸收热量（汽化潜热），因为当液体扩张为气体时分子之间克服相互的吸引力需要能量。 同样，固体在熔解时要吸收热量（熔解潜热）。
Latent Heat - Definition, Types, Formula, Fusion and Vaporization
网页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.
What Is Latent Heat? Definition and Examples - ThoughtCo
网页2019年11月4日 · Latent heat causes hurricanes to intensify. Air heats as it crosses warm water and picks up water vapor. As the vapor condenses to form clouds, latent heat is released into the atmosphere. This added heat warms the air, producing instability and helping clouds to rise and the storm to intensify.

网页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 ().
14.3: Phase Change and Latent Heat - Physics LibreTexts
网页2021年7月11日 · During phase changes, heat absorbed or released is given by \(Q = mL,\) where \(L\) is the latent heat coefficient.
Latent Heat - Summary – The Physics Hypertextbook
网页The specific latent heat (L) of a material…. is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change. is defined through the formula Q = mL. is often just called the "latent heat" of the material. uses the SI unit joule per kilogram [J/kg].
