One mole of an ideal gas is isothermally expanded from 5.0 L to 10.0 L at 298 K. Compute the entropy changes for the
(i) system
(a) in a closed system, reversibly by adjusting the pressure of the surroundings to match the internal pressure of the gas.
(b) irreversibly, freely expanding in a vacuum in an isolated system?
(ii) of the universe if the process is carried out
(a) in a closed system, reversibly by adjusting the pressure of the surroundings to match the internal pressure of the gas.
(b) irreversibly, freely expanding in a vacuum in an isolated system?
