Question I (8 marks) Suppose 2.00 mol ofan ideal gas is contained in a heat—insulated cylinder with a moveable frictionless piston. Initially the gas is at 1.00 atm and OL’C. The gas is compressed reversibly and adiabatically to 2.00 atm. The molar heat capacity at constant pressure. cp. equals 29.3 J/Kmol. Calculate the final temperature ofthe gas. the change in its internal energy All, and the work done on the gas. .3 l a at may f} ; Question 2 (1 7 marks) One mol (1.00 mol) ofan ideal monatomic gas is taken reversiny through the following cycle. Step 1: The gas expands at a constant pressure from a volume of 10.00 L and 2.00 atm to a volume of 20.00 L and 2.00 atm. Step 2: The gas is then expanded adiabatically, to a pressure of 100 atm and a volume of 30.3l 1.. Step 3: Now. the gas is compressed at a constant pressure to volume of l 5. l 6 L and a pressure of l .00 atm. Step 4: Finally, the gas is compressed adiabatically, back to the original conditions of 10.00 L and 2.00 atm. 51) Draw a pressure vs. volume graph olthe above changes. b) Calculate w and q for each step ol‘the process. c) Calculate the total w and q for the complete cycle. 5 d) Calculate the efficiency ol‘the system (8), 3 (D 73 PM. lxuflflj‘kflfe /“/3.b K.
