A student wants to investigate the thermodynamic properties of a system undergoing a non-equilibrium process. The system is initially at a temperature of 300 K and pressure of 1 atm. A sudden expansion of the system causes the pressure to drop to 0.5 atm while maintaining a constant temperature. Calculate the change in entropy of the system during the process assuming ideal gas behavior.
