A process has been proposed whereby an ideal gas is taken from P=10 bar and T=300 K to P=1 bar and T=500K in a closed system. During the process the system performs 1,000 [J] of work and receives 6,430 [J] of heat from the surroundings at a constant temperature of 300 K. The constant pressure heat capacity of the gas cp=30 [J/(mol K)] . Gas constant R=8.314 [J/(mol K)]. (a) (7 pts.) What is the change of molar internal energy [in J/mol] for this process? (b) (8 pts.) How many moles of the ideal gas are there in the system? (c) (10 pts.) What is the change of entropy [in J/K] of the gas? (d) (10 pts.) What is the change of entropy of the surroundings [in J/K]? (e) (5 pts.) Is this process possible according to the second law of thermodynamics?
