Abstract

If heat be supplied at a constant rate to a liquid which is kept at uniform temperature throughout by stirring, and if this liquid lose heat according to Newton's law of cooling, we get dΘ/dt = β/C – αΘ for the differential equation from which to obtain the temperature, Θ, as a function of time. β/c is the rate of heat supply divided by thermal capacity and a Θ the rate of cooling. The surrounding medium is assumed to be at zero temperature. This equation is equally valid if the liquid be replaced by a solid of very high diffusivity. Equation (1) assumes the thermal capacity of the liquid to be independent of temperature.
