Fourier's law of heat conduction states that the rate of heat transfer through a material is proportional to the negative gradient of the temperature and the area through which the heat flows. This fundamental principle describes how heat energy moves from regions of higher temperature to regions of lower temperature, ensuring thermal equilibrium over time.

Thermal equilibrium is a state in which two or more objects in thermal contact no longer exchange energy through heat, resulting in a uniform temperature across the system. It is a fundamental concept in thermodynamics that underlies the zeroth law, which allows the definition of temperature scales.
