Latent heat - Wikipedia
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
Oct 3, 2024 · 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 - Definition, Types, Formula, Fusion and Vaporization
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
Nov 4, 2019 · 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.
Difference Between Latent Heat and Sensible Heat | Definition ...
Oct 14, 2017 · The main difference between latent heat and sensible heat is that latent heat is defined for a system that undergoes a phase change of matter whereas sensible heat is defined for a system that has no change in the phase of matter.
Specific latent heat - Energy, temperature and change of ... - BBC
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 has two specific latent...
Latent heat - Energy Education
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.
14.7: Phase Change and Latent Heat - Physics LibreTexts
\(L_{\mathrm{f}}\) and \(L_{\mathrm{v}}\) are collectively called latent heat coefficients. They are latent, or hidden, because in phase changes, energy enters or leaves a system without causing a temperature change in the system; so, in effect, the energy is hidden.
Latent Heat – Definition, Examples and Formula - Vedantu
The latent heat of fusion or melting, of a solid, is the quantity of heat in joules required to transform a solid, at its melting point, to a liquid without any variation in temperature. The latent heat of fusion of ice is 3.34 x 10⁵ joules per kilograms (or, 3.34 x 10⁵J/Kg).
Temperature changes and energy - AQA Specific latent heat - BBC
Specific latent heat is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature. As there are two...
