(b) Calculate the heat transfered during the expansion.
Q=
✓ J
(c) What is the change in entropy of the gas?
AS
=
✔J/K
gas
(c) What is the entropy change of the thermal reservoir?
=
AS reservior
✔J/K
(d) What is the entropy change for the gas+reservior system?
AS system
✔J/K
Hint: For an isothermal process how is the heat transferred by an ideal gas related to work? What is
the formula for work done by an ideal gas during isothermal expansion?
