For this problem, let’s apply thermodynamics to elastic materials (e.g., rubberbands). The tension force f exerted by a rubber band depends on both the temperature T and the stretching displacement L. What is the work associated with stretching or contracting a rubber band? [Hint: Recall the definition of work used in physics.]

1 kg of a fluid expands reversibly according to a linear law from 4.5 bar to 1.6 bar; the initial and final volumes are 0.004 m3and 0.02 m3. The fluid is then cooled reversibly at constant pressure, and finally compressed reversibly according to a law pV = constant back to the initial conditions of 4.5 bar and 0.004 m3. Determine the work done in each process and the net work of the cycle. Sketch the cycle on a p-v diagram.
The efficiency of all real engines are less than that of the carnot engine. Why?
