WebOct 8, 2014 · Oct 8, 2014. Boiling water is an endothermic process, which supplies heat to the water molecules, increasing their potential energy. The applied heat causes the water molecules to move further away from each other without causing any increase in overall temperature. More specifically, the applied heat goes into breaking the intermolecular … WebTo boil 1 kg of water we need 2.3 x 106 J. Each hydrogen bond requires an input of 0.2 eV to break it. Converting that to Joules we get (0.2 eV) x (1.6 x 10-19 J / 1 eV) = 0.32 x 10-19 J per hydrogen bond. So if all our energy of boiling is breaking hydrogen bonds, we must be breaking N = (2.3 x 106 J) / (0.32 x 10-19 J/bond) ~ 7 x 1025 bonds.
