There are two piston-cylinder systems that each contain 1 kg of an idea gas at a pressure of 300 kPa and temperature of 350 K. The two systems then undergo two different processes: System 1 undergoes process 1 as follows:
Isobaric heating to 500 K, then compressed to a pressure of 500 kPa and a temperature of 600 K.

System 2 undergoes process 2 as follows:
Directly compressed in one step to a pressure 500 kPa and a temperature of 600 K

We "measure" the entropy of each system before and after the process. Which system had the biggest entropy change?

a. System 1
b. System 2
c. Entropy change is the same for both systems
