1. Changes in the free energies [8 pts] An ideal gas undergoes an expansion at a constant temperature of T = 300 K. The gas begins at a volume 2m³ and a pressure of 300 Pa, ending with a volume 3m³ and a pressure of 200 Pa. (a) [2 pts] What is the change in the internal energy of the gas during the process? Explain. (b) [2 pts] Determine the change in the enthalpy of the gas during the process. (c) [2 pts] During the expansion the entropy of the gas increases by +0.81 J/K. How much heat flows into the gas during the process? (d) [2 pts] Determine the change is the Gibbs free energy of the gas during the expansion.
