Which one has a larger final entropy, reversible isothermal
process or reversible adiabatic process when expanding to the same
final volume for an ideal gas?
What do you assume the entropy S for a perfect crystal when T =
0?
Is the S(0) still zero if the crystal is not perfect? Why?
How to calculate dS when under the constant pressure and
cp is given?
How to calculate the entropy of H2O at 500 K?

A diatomic gas containing 1.5 moles expands in an isothermal
process from b to c. From c to a the gas is compressed from a
volume of 0.1m3 to 0.04m3 at a constant pressure of 100kPa and from
a to b the gas goes through an isochoric process. Determine:
(3 pts) Determine highest temperature and the lowest temperature
reached by the gas.
High
Low
(6 pts) Determine how much heat is added to the gas in each
cycle and how...
