The definition of the latent heat of fusion is the amount of energy needed to convert a specific amount of a solid into a liquid (vice versa) at a fixed temperature. The heat of fusion definition states that the phase transition between solid and liquid occurs when the temperature of the ...

latentheat 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. Condensationofgas to liquidrequires removal rather than addition ...
In subject area: Chemistry For example, a heat capacity, Cp, provides information regarding the entropy or enthalpy fluctuation of the system, while its integrated quantity, the entropy or enthalpy, gives the global average. From: Solution Thermodynamics and its Application to Aqueous Solutions (Seco...
For example, when a solid changes to its liquid form (i.e., the change from ice to water), the enthalpy change is called the heat of fusion. When a liquid changes to its gaseous form (i.e., the change from water to water vapour), the enthalpy change is called heat vaporisation. ...
Definition of Latent Heat: Normally, when we add or remove the heat energy from some object, the temperature of the object changes. But during the phase changes, the temperature of an object remains constant. This is because of the fact that energy is required for an object to change phases...

To obtain a numerical simulation of heat transfer during the welding process the following heat conservation equation (1) which accounts for the latent heat of fusion and solidification must be solved:ρcp∂T∂t−q−λx∂T∂x+λy∂T∂y+λz∂T∂z=0where T is the temperatur...
