The molar heat capacities of gases are not perfectly constant, as we've assumed, but increase slowly with temperature. An empirical formula for the molar heat capacity at constant volume of nitrogen is Cv = (20.6-1.6 x 10-³T+8.0 x 10-672) J/mol K, where T is in K. Part A What is the entropy increase of the gas if 4.2 g of nitrogen in a rigid container are slowly heated from 300°C to 500°C? Express your answer with the appropriate units.
