Note that this equation assumes . all. of the water vapor in the air parcel has condensed out. The temperature increase due to latent heat conversion to sensible heat when the water condenses is therefore (2) Notice that the heat capacity used here is a combination of the heat capacity of dry air and condensed water.

Equation (4) and. Equation (5) and. heat needed to warm the water from the melted ice. but. so. heat needed to warm the water from the melted ice = Equation (6) Substituting equations (4), (5) and (6) into Equation (3) gives: Equation (7) We assume that all the ice will melt in this experiment. So, the mass of the water from melted ice is the ...

BONUS: For water, the value for the latent heat of vaporization is 6.8 times greater than the latent heat of fusion. Imagine we were adding heat at a constant rate to a block of ice in a beaker on a hot plate, and it took 4 minutes for the ice to melt completely.

The amount of heat needed to melt a solid depends only on the mass of the solid and the latent heat of fusion of the solid (to fuse means to melt). We have: Equation (1) where. the amount of heat absorbed by the solid to melt it. the mass of the solid. the latent heat of fusion measured in Joules/g

Thus, the latent energy is released over a range of about 10 F, and the formulation above is a step-change simplification of a continuous process. Using this definition of latent heat, a more general equation for combustion efficiency is:

The two main steps are: (a) determine where heat is released by solving equation (2) for the net production of precipitation and identify regions where > 0 (saturation) and (b) compute the magnitude of the latent heat release using equation (4).
