Question

2. One mole of nitrogen contained in a rigid and insulated tank at 300 K is
stirred by a paddle wheel, which is operated by a 60 W electric motor for 2
mins. If the molar heat capacity at constant volume for nitrogen is given by
Cy= 18.956 + 4.93 x 10-3 T where Cy is in J/mol Kand T is in K. Calculate the
change in internal energy and entropy of nitrogen.
