    The Molar heat capacities of nitrogen at constant pressure and constant volume are 29.11kJ/k mole K and 20.81 kJ/kmole K, respectively. When 5 gram of nitrogen is heated from 290 to 310 K (i) the decrease in its internal energy and (ii) the external work done are, (Molecular weight of nitrogen = 28) A) 74.32 J, 29.64 J B) 29.64 J, 74.32 J C )64.32 J, 19. 64 J D)94.32J, 39.64 J
