WebLet's see. 4 times 200 is 800, 800 times 100; yeah, that's about right. Now, we're dealing with 100 degree water vapor, and we have to turn that 100 degree water vapor to 110 degree vapor. So we use the specific heat of vapor. 1.89 joules per gram Kelvin. Multiplied by the amount of vapor we're dealing with, 200 grams. WebThis heat supplied to the solid at its melting point is the latent heat of fusion. It is defined as the heat energy required for completely changing 1 kg of a solid into a liquid state at atmospheric pressure. The term latent …
WebHeat Of Fusion. The amount of energy necessary to change a unit mass of compound from its solid phase to liquid phase at constant pressure and temperature is called heat of fusion. While transferring one phase to another, the heat is absorbed or supplied to the system. It can be expressed as follows, WebDec 8, 2024 · The heat of vaporization formula is the heat required to trigger the vaporization of a substance divided by the mass of the substance: Hv = q/m H v = q / m.
