Under normal atmospheric pressure, nitrogen boils (and condenses) at - 196°C. When 7.7 g of nitrogen gas at -196°C was put into a dewar flask nitially at -260°C, their temperatures reach -210°C. If the specific heat capacity and heat of vaporization of nitrogen are 1.04 J/g-°C and 200 J/g, espectively, determine the heat capacity of the dewar flask.
