Given the PV diagram of a fixed quanity of CO2 assumed to be an ideal gas. The temperature at point a A is 35 degrees celsius. What is the total mass of CO2? What ist he temperature at point C in degrees celsius? What is the heat added to the gas over the ABCA cycle? If 3200 J of heat flows out of the system when the system is taken in a straight path from C to A, what is the change in enteral energy along that path?

How much heat does it take to increase the temperature of 2.00 moles of an … Part A: ideal monatomic gas from 17 degrees C to 37 degrees C if the gas is held at constant volume? Part B: ideal diatomic gas from 17 degrees C to 37 degrees C if the gas is held at constant volume? (express both answers in joules)

Part A: 10 moles of ideal gas initially at 10 atm and 250 K is expanded isothermally and reversibly to a final pressure of 2 atm. Calculate W, AU, and Q in Joules. Part B: The same gas in problem A, starting in the same initial state, is expanded isothermally against a constant external pressure of 2 atm, to a final pressure of 2 atm. Calculate W, AU, and Q in Joules for this irreversible process. Part C: The same gas in part B, starting in the same initial state, is expanded isothermally to a final pressure of 2 atm. The process is carried out in 4 stages. First the gas is expanded against a constant pressure of 8 atm, to 8 atm. Then the gas is expanded against a constant pressure of 6 atm, to 6 atm. Then the gas is expanded against a constant pressure of 4 atm, to 4 atm. Finally, the gas is expanded against a constant pressure of 2 atm, to 2 atm. Calculate W, AU, and Q in Joules for the 4-step process.

I need the answers for d-f but please also answer a-c as well.
