In this week's experiment, the heat of vaporization of liquid
nitrogen is determined by measuring the change in temperature of a
known sample of warm water when liquid nitrogen is added.
In one experiment, the mass of water is 104 grams,
the initial temperature of the water is
69.3oC, the mass of liquid nitrogen
added to the water is 60.6 grams, and the final
temperature of the water, after the liquid nitrogen has vaporized,
is 41.3oC.
