Latent Heat of Vaporization: An Example Lesson Summary Frequently Asked Questions What causes latent heat? Latent heat is the amount of heat absorbed or released divided by the mass of a substance that is changing phase. Latent heat is caused by overcoming the intermolecular forces that hold the...
Heat generated, for example, in a spacecraft under zero gravity conditions and different accelerations is discharged through an evaporation heat exchanger connected to at least one active coolant circulation circuit. The heat exchanger has a bundle of tubes axially arranged inside a cylindrical ...
Heat of Vaporization refers to the amount of heat required to convert 1 gram of a liquid into vapor without a change in temperature. It is the highest for water and is a type of latent heat associated with a change in state without a change in temperature. ...
Liquids - Latent Heat of Evaporation Latent heat of vaporization for fluids like alcohol, ether, nitrogen, water and more. The input energy required to change the state from liquid to vapor at constant temperature is called the latent heat of vaporization. When a liquid vaporize at the normal...
Where L is the latent heat, q is the energy released or absorbed, and m is the mass of the substance that's changing phases. There are a total of four types of latent heats: The latent heat of vaporization, which is the energy required to convert a liquid to a vapor at a specific...

Heat transfer through the membrane by conduction and by movement of vapor across the membrane (latent heat of vaporization). The influence of mass transfer on the heat transfer can be ignored [75,97,107–109,114] (3.29)Qm=kmδTf,m−Tp,m+J△Hv (3.30)Qm=hmTf,m−Tp,m+J△Hv where...
(ca. 1757)n.The quantity of heat necessary to change 1 g of liquid to vapor (latent heat of vaporization) without change of temperature; heat necessary for change of state being negative or positive heat (e.g., fusion, evaporation, and melting). For example, the latent heat of fusion...
