In the plane a reversible transformation is a curve, and the heat received is the area under it: . A reversible isotherm is horizontal, an isentropic (reversible adiabatic) vertical; a reversible cycle encloses an area equal to the heat received and hence, by the first law, to the work delivered (Chapter 24).
