On process 3 the gas expands at constant pressure from initial volume 1.00 m^3 to a final volume of 3.00 m^3. On process 4 the gas is heated at constant volume from an initial pressure of 106 kPa to a final pressure of 212 kPa .
Part A: How much heat is added to the gas during these two processes? (kJ)
Part B: How much work does the gas do during this expansion? (kJ)
Part C: What is the change in the internal energy of the gas? (kJ)
