waterA simple model is introduced to interpret the heat of vaporization of water, which assumes the gaseous state as an ideal gas and the condensed state as an ideal "solid." Making the approximations ω j kT and ω i kT simultaneously for the vibrational energies of the molecules in the ...

The latent heat flow due to moisture in air can be expressed in SI-units (metric) as Ql = hwe ρ q Δx / 3600 (2) where Ql = latent heat flow (kW) hwe = latent heat of vaporization of water (2454 kJ/kg - in air at atmospheric pressure and 20 oC) ρ = air density ...

fusion and vaporization. Hence the lat heat of sublimation for water is about (334 + 2260) kJ/kg = 2600 kJ/kg You could refer to the following web-page read the para. under "Some Technical Stuff": usatoday/weather/wlatent 参考: en. *** /wiki/Enthalpy_of_vaporization ...
human body is dissipated through the skin to the environment as sensible, or dry, heat and as latent heat.Latent heat lossrepresents theevaporation of waterin the respiratory system and from the skin. Thus latent heat depends on the moistness of the skin andrelative humidityof surrounding air[...
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 ...
Tags Heat Latent heat Temperature Vaporization Oct 31, 2011 #1 worwhite 25 0 Hi, I would like to ask, why is it that the specific latent heat of vaporization of water at, say 10 degrees Celsius, is considerably higher that at 100 degrees Celsius? It would be great if you could prov...
