Heat of Vaporization-the amount of heat required to convert unit mass of a liquid into the vapor without a change in temperature. For water at its normal boiling point of 100 C, the heat of vaporization is 2260 J g-1. 2260 J of heat must be absorbed by the water. Conversely, when 1 g of steam at 100 C condenses to give 1 g of water at 100 C, 2260 J of heat will be released to the surroundings.
Theory The heat of vaporization of a liquid is the energy that must be supplied in order to convert a unit mass of the liquid to the gas phase. A typical unit is Joules/gram (J/g). Liquid nitrogen at atmospheric pressure has a boiling point of 77.3 K and remains at its boiling point throughout the experiment.se Igor to produce graphs of mass versus time and determine the three rates of vaporization via a linear fit to the data using Igor. Remember, for each rate you are making a linear fit to a part of the data. 6. Calculate the latent heat L and compare it to the accepted value of 199.5 J/g for liquid nitrogen.
