Liquid nitrogen is the liquid form of the diatomic nitrogen gas. We place 50\ grams of liquid nitrogen in a rigid, 2-liter container at 77.3K (thats the boiling point for\ liquid nitrogen). We then add 20kJ of heat to the liquid nitrogen. The resulting gas is then\ allowed to expand at constant pressure to a volume of 5 liters. How much work does the gas\ do while expanding? Note that nitrogen gas has a molar mass of 28 g/mol and its latent\ heat of vaporization is 200 kJ/kg. Also assume that the container is empty except for the\ nitrogen.\ 2
