Question

A Carnot engine operates using 2.00 moles of an ideal gas between a hot temperature of
470.0 K and a cold temperature of 310.0 K. Before the isothermal expansion, the volume
of the engine is 10.0 L and after the isothermal expansion, it is 40.0 L. You may assume
that the specific heat capacity of the ideal gas is cV = (3/2)R.
2. (a) Draw a diagram of the cycle in the pressure-volume (p-V) plane, label all axes
(with units), and provide numerical values of all coordinates (p,V) of the four
points defining the cycle. Use solid lines and arrows to denote the paths of the
pressure-volume changes.
2. (b) What is the work per cycle ?wTOT done by this Carnot engine?
2. (c) What is the change in entropy ?S caused by the isothermal gas expansion in the
first step of this Carnot cycle?
2. (d) What is the efficiency of this Carnot engine? Briefly state how you could improve
the efficiency of this Carnot engine in one or two sentences.
