Question

9.186E-1 moles of an ideal diatomic gas undergoes a transition from a to c along the diagonal path in the figure. The temperature of the gas at point a is 1310 K. During the transition, what is the change in internal energy of the gas? How much heat is added to the gas in going directly from a to c? How much heat must be added to the gas if it goes from a to c along the indirect path abc?

Answer 1

Without the figure....
