One mole of a monatomic ideal has at a temp of 500K and 6atm pressure is subjected to the following changes: (all are reversible changes)
1. gas expanded isothermally (and reversibly) to 5atm.
2. after STEP1, gas expanded adiabatically and reversibly until the pressure is 4atm.
3. After STEP2, gas is compressed isothermally and reversibly to 4.800atm.
4. After STEP3, gas is compressed adiabatically and reversibly to a pressure of 6 atm, returning the gas to a temperature of 500K.
Question: Compute w, q, and delta_U for the entire process.
