Carnot's function

(Thermo-dynamics) a relation between the amount of heat given off by a source of heat, and the work which can be done by it. It is approximately equal to the mechanical equivalent of the thermal unit divided by the number expressing the temperature in degrees of the air thermometer, reckoned from its zero of expansion.

Thomson first realized that the acceptance of the inter-convertibility of heat and work did not have to discard Carnot's Principle, a corollary of which is Carnot's function, [micro](t), a function of temperature.
