    I know what this law says, but I don´t know where does it comes from. Could somone please help me with the derivation of this law?
    Thanks in advance.

    It's purely a matter of experimental evidence- heat flows from a warmer body to a cooler one at a rate proportional to the difference in temperatures.

    you may derive this law from Stefan's law of black body radiation with the approximation that the temperature difference between the body and surrounding is not much large.
