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.
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.
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.
1 day ago · This explains the concept of latent heat which is the extra heat required to change the state of a substance, for example, if a substance is in the solid-state, latent heat provides the extra energy to change its state to liquid and then from the liquid state to the gaseous state.
Apr 15, 2024 · 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. It can also refer to the quantity of heat energy received or emitted during a phase transition.
Nov 4, 2019 · Specific latent heat ( L) is defined as the amount of thermal energy (heat, Q) that is absorbed or released when a body undergoes a constant-temperature process. The equation for specific latent heat is: L = Q / m. where: L is the specific latent heat. Q is the heat absorbed or released. m is the mass of a 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.
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.
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 .
Nov 21, 2023 · Latent heat is the amount of heat absorbed or released divided by the mass of a substance that is changing phase. Latent heat is caused by overcoming the...
