What is Latent Heat? Latent Heatrefers to the amount of heat energy required per unit mass in order for a substance to undergo a physical change. It changes the movement of molecules. Additionally, each substance has a specific latent heat value. In phase changes, such asfreezing,boiling, or...
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 ...
An expression for the latent heat of vaporization of a fluid is formulated employing renormalization-group theory predictions for the thermodynamics of fluids in the vicinity of the critical point. A least-squares fit of the latent heat data of water is made using the general and relatively simple...
HeatandMassTransferIn order to determine the energy needed to artificially dry a product, the latent heat of vaporization of moisture in the product, hfg, must be known. Generally, the expressions for hfg reported in the literature are of the form hfg = h(T)f(M), where h(T) is the ...
Just like specific heat capacity and latent heats, conductivity is a property specific to the material at hand,. It is denoted by the Greek letter κ (kappa) and is usually looked up in a table. The SI units of conductivity are watts/meter × Kelvin (W/mK). ...
