WebApr 5, 2016 · Latent heat of vapourisation of water at 1 bar, 100 ∘ C is 2257 k J k g. Which means, that much heat is required to break inter-molecular forces and turn into gasoeus phase. As pressure on molecules increases they require more heat to overcome the pressure force acting or to escape and thus latent heat required is more. WebThe heat energy (enthalpy of evaporation) needed at 7 bar g to vaporize the water to steam is actually less than required at atmospheric pressure. The specific enthalpy of vaporization decreases with steam pressure. The evaporation heat is 2046.53 kJ/kg at 7 bar g. Note!
