Fouriers Law of Heat Conduction

Fourier's Law of Heat Conduction states that the rate of heat transfer through a material is directly proportional to the temperature difference across that material and the area through which heat is flowing. It also depends on the material's thermal conductivity, which indicates how well it conducts heat. In simple terms, if one side of an object is hot and the other is cold, heat will flow from the hot side to the cold side, and the greater the temperature difference, the faster the heat transfer occurs.
