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...

4. 50 mol of nitrogen gas initially at 10°C and 100 bar are heated at constant pressure to a final temperature of 300°C. Using an appropriate generalized correlation calculate the amount of heat required for the process. Note that nitrogen is not an ideal gas under these conditions. Over this temperature range you may assume Cp of nitrogen to be constant equal to 30 J/mol K

A sample of n moles of a monatomic ideal gas is expanded isothermally and reversibly at a constant temperature T from a volume V to 3V. Note that since the temperature of the gas is constant, the internal energy will remain constant. a) Write an expression for the change in entropy ΔS for the system. b) The sample has 7 moles of gas and is kept at a temperature of 305 K. The volume is changed from 0.065 m3 to...
