The gas has an initial volume 0.010 m3 at 100 kPa pressure and its temperature is initially 300 K. The gas is cooled at constant pressure until its volume is 0.006 m3, Calculate the i. Final temperature of the gas [ans: 180 K] ii. Work done on the gas [ans: -400 J] iii. Number of the moles of gas [ans: 0.4 mol]

Look at the P-V diagram below (Diagram 1). Calculate the work done by the gas for the paths A, B and C. Assume that in Diagram 1, P1 = 1 atm, P2 = 4 atm, V1 = 5 L, V2 = 15 L. a) WA = 1013 J, WB = 0, WC = -2533 J b) WA = 0.01 J, WB = 0, WC = -0.025 J c) WA = 2533 J, WB = 0, WC = -1013 J Calculate the work done by the gas for the path AB in Diagram 2. Use the data: P1 = 1 atm, P2 = 4 atm, V1 = 5 L, V2 = 20 L. (Path AB is an "isothermal" which means the temperature T is constant on this path). a) 0.012 J b) 1220 J c) 0.0278 J d) 2809 J
