156 SOLUTIONS

d) During adiabatic compression, the entropy is constant, so from (S.4.52.7)

and we have

e) The work done is given by the change in internal energy since the
entropy is constant:

From (S.4.52.11), we arrive at

Critical Parameters (Stony Brook)

At the critical point we have the conditions

Now, from we have

and using (S.4.52.4) and (S.4.52.7), we get

So, (S.4.52.8) becomes

4.53
