Plotting PV curves for isothermal and adiabatic changes is also covered in the worksheet PV diagram in geogebra but plotting the closed curves of a Carnot cycle is a bit clumsy so here is an alternative (better) method. In the previous example the curves are plotted by tracing a point whose position is defined by the equations for isothermal and adiabatic changes. In this example the lines will be plotted directly from...
