Question
Use these steps to answer the questions below:
Step 1: A sample of monoatomic ideal gas, initially at pressure P1 and volume V1, expands isothermally and reversibly to a final pressure P2 and volume V2
Step 2: The ideal gas is compressed isothermally back to its initial conditions using constant pressure.

1) The work done will be negative, as the gas expands and the work is done by the system.
2) Qsystem: it will be positive (as the system is expanding)
3) W system (cycle) = positive , work done on the system
4) dU (step 1) = 0, the change in temperature is zero so the internal energy change will be zero
5) delta U (cycle) = zero , isothermal
