The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. The vaporization is the opposite process of condensation. The heat of condensation is defined as the heat released when one mole of the subs ...Prem Datt...
The latent heat of condensation refers to the heat that is released when a specific amount of vapor condenses and returns to the liquid phase at a fixed temperature. An example of such is the formation of morning dew. What is latent heat energy? Latent heat is the heat needed to cause ...
Types of latent heat are: (i) latent heat of vaporisation (Δhv): heat required to vaporise a liquid; (ii) latent heat of fusion (Δhf): heat required to melt a solid; and (iii) latent heat of sublimation (Δhs): heat required to directly vaporise a solid. Condensation of gas to...
In our atmosphere and at the Earth’s surface, the phase changes are those associated with water (i.e., evaporation, condensation, and/or, sublimation). The amount of energy absorbed or released is proportional to L, the latent heat of the phase transition: (4)QL=LΔQ where ΔQ is ...
Related to latent heat:Latent heat of fusion,Latent heat of vaporization latent heat n. The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure. Also calledheat of transformatio...
The latent heat of vaporization of steam is 540 calories per gram, absorbed during vaporization or given up during condensation. For a substance going directly from the solid to the gas state, or the reverse, the heat absorbed or given up is known as the latent heat of sublimation. The ...
This is the latent heat. Once all the water is turned into vapor, a further transfer of heat will simply increase the temperature again. Condensation is the reverse process of vaporization, where gas turns into liquid. The latent heat released during condensation is equal to the latent heat ...
