Web15 mei 2024 · We need only evaporate 1μm of liquid if it is spread over 1m 2, and we need to remove 10000μm (i.e. 1cm) if it is spread over 1cm 2. We need to know the air velocity. At zero velocity the rate of evaporation is very close to zero because molecular diffusion is amazingly slow. WebIt actually evaporates slowly compared to its very low molecular weight which is 18 g/mole for H2O. Its boiling point is 100 C. The next similar chemical is H2S, its molecular weight is 34 g/mole and its boiling point is -60 C, so it is a gas above -60C. H2S is heavier than …

Web24 jan. 2006 · According to my predictions, the heptane, due to its longer chain structure, would have a greater instantaneous dipole, which would mean greater intermolecular attraction and higher boiling point. This would have suggested that there would have been a greater temperature drop in the heptane than the hexane because more energy would … WebExample - Calculate heat required to evaporate 10 kg of water. The latent heat of evaporation for water is 2256 kJ/kg at atmospheric pressure and 100 o C. The heat required to evaporate 10 kg can be calculated as. q = (2256 kJ/kg) (10 kg) = 22560 kJ
