(a) What sign for ?S do you expect when the volume of 0.200 mol of an ideal gas at 27 °C is increased isothermally from an initial volume of 10.0 L?
(b) If the final volume is 18.5 L, calculate the entropy change for the process.
(c) Do you need to specify the temperature to calculate the entropy change? Explain.
