The molar heat capacity of N2(g) in the range 200K to 400K is given by Cpm (J/Kmol)= 28.58+3.77*10^-3 (T/K). Given that the standard molar entropy of N2(g) at 298K is 191.6 J/Kmol, determine q, w, change in enthalpy (H), change in internal energy (U), and change of entropy of the system (Ssys) when the temperature is raised from 25C to 100C under a) constant pressure and b) constant volume.
