tion in a specified direction is proportional to the temperature gradient, which is the rate of change in temperature with distance in that direction. Heat conduction in a medium, in general, is three-dimensional and time depen-dent, and the temperature in a medium varies with position as well as time, that is, T T(x, y, z, t).
