2. A 1.00L piston with 1.00mole of an ideal gas at 298.0K and1.00bar is isothermally and reversibly compressed to a final volumeof 0.100L, then irreversibly expanded in 1 step to its originalvolume with an applied pressure of 1.00bar.
a. (6 pts) Calculate the change in heat for the system (q sys)for the compression and expansion steps.
b. (6 pts) Calculate the change in entropy for the compressionand expansion steps.

Thanks!
c. (6 pts) Calculate the net change in entropy for thecompression and expansion steps together.
d. (6 pts) Is there a net change in entropy for the system? Ifso, why; if not, why not?
e. (6 pts) Is there a net change in the entropy for thesurrounding? If so, why; if not, why not?
