Specific enthalpy of vaporization of water
WebJan 14, 2024 · But then among all the data, which are truly interesting, there is one other thing that stands out: the heat of vaporization of water is 40.8 kJ/mol, whereas for ammonia, it is only 23.5 kJ/mol. So water can still be considered an extreme molecule. Share Improve this answer Follow edited Jan 15, 2024 at 20:31 answered Jan 14, 2024 at 14:30 WebTherefore the specific enthalpy of water at 0 bar g (absolute 1 bar ) and 100 oC is 417.51 kJ/kg. Another 2257.92 kJ of energy is required to evaporate 1 kg of water at 100 oC into 1 kg of steam at 100 oC. Therefore at 0 bar g ( absolute 1 bar) the specific enthalpy of vaporation is 2257.19 kJ/k g.
