A physics student wants to calculate the entropy change that occurs when a thermally isolated container is filled with 1.50 mol of an ideal gas at a temperature of 300 K and a pressure of 2.00 atm, and is then compressed isothermally to a final pressure of 5.00 atm. Calculate the resulting change in entropy.
