Water standing in the open at 32.0°C evaporates because of the escape of some of the surface molecules. The heat of vaporization (539 cal/g) is approximately equal to en, where e is the average energy of the escaping molecules and n is the number of molecules per gram. (a) Find e. (b) What is the ratio of e to the average kinetic energy of H2O molecules, assuming the latter is related to temperature in the same way as it is for gases?
