WebApr 9, 2024 · The latent heat of fusion is also called as the enthalpy of fusion. It refers to the amount of the energy which needs to be supplied to a solid, generally in the heat form. This aids in triggering a change in the physical state and, in turn, converts it to a liquid. Consider, for example, the specific heat of fusion of water of 1 kg, which ... WebJan 24, 2024 · Importance of Latent Heat in our Daily Life. Ice is used to store the food items such as fish, meat, etc. Due to the high latent heat of vapourization, the hot vapour is used in many processing industries to carry heat. The latent heat of fusion of ice cream should be large enough to avoid rapid melting. Our body maintains the temperature by ...
WebDec 20, 2024 · latent heat: [noun] heat given off or absorbed in a process (such as fusion or vaporization) other than a change of temperature.
WebLatent heat, also called heat of transformation, is the heat given up or absorbed by a unit mass of a substance as it changes from a solid to a liquid, from a liquid to a gas, or the reverse of either of these changes. It is called latent because it is not associated with a change in temperature. Each substance has a characteristic heat of ... motorcycle graphics kit hs codeWebSpecific latent heat is characterized as the measure of heat energy (heat, Q) that is consumed or discharged when a body experiences a steady temperature process.
