Consider a gas (known R and cv) initially at known P1, ?1, and T1 that is compressed to a final (known) pressure ?2 very slowly. (a) What assumption can you reasonably make for this very slow compression process? (b) Find the entropy generated during this process (hint: try to write a symbolic expression for the entropy generation in terms of only the given information). What can you conclude from the entropy generation you found? (c) How would your solution change if the system boundary was expanded to include the cylinder at a temperature Tc
