Round everything to four decimal places. A constant temperature compression process is done for 3 moles of an ideal gas initially at 500°C and 4 bar. The gas will reach a final pressure of 8 bars. During compression, heat is released by the process to a sink of 25°C. If the irreversible/real work to be used for compression is 40% more than the work for a reversible one, calculate: a. the entropy change of the gas, b. the entropy change of the surrounding, c. the entropy generated.
