(1) 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...
