Question: A. Calculate the work, w , (in J) when 8.9 litre of an ideal gas at an initial pressure of 83.1 atm is expanded to

A. Calculate the work, w, (in J) when 8.9 litre of an ideal gas at an initial pressure of 83.1 atm is expanded to a final pressure of 0.66 atm against a constant exteral pressure of 0.66 atm. Assume that the initial pressure and the final pressure have been measured at the same temperature.

B. Part 3 of a 5 part question: Calculate the heat q when 6.3 litre of an ideal gas at an initial pressure of 75.6 atm is expanded or compressed to a final volume of 75.6 litres against a constant external pressure of 6.3 atm. Assume that the initial and the final temperature of the gas is the same. Give your answer in J.

C. Part 4 of a 5 part question: Calculate the work w when 3 litre of an ideal gas at an initial pressure of 30.1 atm is expanded or compressed isothermally to a final volume of 30.1 litres reversibly. Give your answer in J.

D. 0.15 litre of an ideal monatomic gas (C_v,m = 3R/2) initially at 32C and 23 atm pressure undergo an expansion against a constant external pressure of 0.94 atm, and do 1.1 kJ of work. The final pressure of the gas is 0.94 atm. Calculate the change in enthalpy,H. Report your answer in J.
