Initially 1.300 mol of an ideal gas in a container occupies a volume of 2.50 l at a pressure of 3.30 atm with an internal energy U1 = 592.8 J. The gas is cooled at a constant volume until its pressure is 2.00 atm. Then it is allowed to expand at constant pressure until its volume is 5.50 l. The final internal energy is U2 = 790.4 J. All processes are quasi static. Draw this process on a PV diagram. What is the work done by the gas?
Find the heat added during this process.
