It takes way less energy to heat water to 90ºC than to 100ºC, so the relative amounts of energy required to boil ethanol vs. water are actually as large as stated in the video. It's not really intuitive, but it's one of the odd things about water ... bark beauty
How much energy is required to boil and maintain boiling …

The molar enthalpy of fusion of ice is thus +6.01 kJ mol –1, and we can write. H 2O(s)0oC → H 2O(l) Hm = 6.01 kJ mol. Selected molar enthalpies of fusion are tabulated in Table 10.10.1. Solids like ice which have strong intermolecular forces have ... WebTemperature-dependency of the heats of vaporization for water, methanol, benzene, and acetone The enthalpy of vaporization(symbol ∆Hvap), also known as the (latent) heat of vaporizationor heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. barkbath manual
