WebExample #4:Using the heat of vaporization for water in J/g, calculate the energy needed to boil 50.0 g of water at its boiling point of 100 °C. Solution: multiply the heat of vaporization (expressed in J/g) by the mass of the water involved. (2259 J/g) (50.0 g) = 112950 J = 113 kJ WebThe vast majority of energy needed to boil water comes right before it's at the boiling point. 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 ...
