PASSAGE
A student measures the entropy changes for three different processes involving the same substance at the same initial and final temperatures. Process A is a reversible isothermal expansion. Process B is an irreversible free expansion (expansion into vacuum). Process C involves heating the gas at constant volume to a higher temperature, then cooling at constant pressure back to the original temperature.
Which statement correctly compares the entropy changes for these three processes?
