An engine operates in a Carnot cycle. At point A in the cycle, 2.34 mol of a monatomic ideal gas has a pressure of 1,400 kPa, a volume of 10.0 L, and a temperature of 720 K. The gas expands isothermally to point B and then expands adiabatically to point C, where its volume is 24.0 L. An isothermal compression brings it to point D, where its volume is 15.0 L. An adiabatic process returns the gas to point A.

(a) Make a table providing the pressures, volumes, and temperatures at each of the four points in the cycle. Show your calculations and explain your reasoning, but only provide the values in the table.

(b) Draw a PV Diagram for this engine, with the axes labelled appropriately.

(c) Make a table listing the energy transfer by heat (Q), work done on the gas (W), and the change in internal energy of the gas for each of the four processes in the cycle. Again, show your calculations and explain your reasoning, but only provide the values in the table.

(d) What is the efficiency of this engine? How could you make the engine more efficient?

Carnot engine operating

The oceans in the tropics have substantial surface-to-deep-water temperature gradients. Depending on location, relatively constant temperature differences of 15 to 25oC can obtain for depths of 500 to 1.000 m. This provides the opportunity for using cold (deep) water as a heat sink and warm (surface) water as a heal source for a power cycle. The technology is known as "OTEC (Ocean Thermal Energy Conversion).(a) Consider a location where the surface temperature is 27oC and the temperature at a depth...
