Heat current

A heat current is a kinetic exchange rate between molecules, relative to the material in which the kinesis occurs. It is defined as $\frac{dQ}{dt}$ , where $Q$ is heat and $t$ is time.

For conduction, heat current is defined by Fourier's law as

where

The above differential equation, when integrated for a homogeneous material of 1-D geometry between two endpoints at constant temperature, gives the heat flow rate as:
