Problem 2

1.00 × 10-2 mol of argon gas is utilized as the operational fluid in a thermal engine. The cyclic process of the thermal engine is represented in the pV diagram below. Calculate the net work done by the gas, the heat energy added to the gas, and the variation in the internal energy during the cycle. The temperatures at points A, B and C respectively are: TA = 7.22×102 K, TB = 1.20×103 K, TC = 9.80×102 K and the volume at point C is VC = 543 ×10-6 m3.
