Consider the expansion of 60.0 moles of a monatomic ideal gas along processes 1 and 2 in the figure. On process 1 the gas is heated at constant volume from an initial pressure of 106 kPa to a final pressure of 212 kPa . On process 2 the gas expands at constant pressure from an initial volume of 1.00 m 3  to a final volume of 3.00 m 3 .

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)
