Newton’s law of heating and the heat equation [PDF]
Involve, a Journal of Mathematics, 2009 Newton’s law of heating models the average temperature in an object by a simple ordinary differential equation, while the heat equation is a partial differential equation that models the temperature as a function of both space and time. A series solution of the heat equation, in the case of a spherical body, shows that Newton’s law gives an accurate ...
