WebNewton’s law of cooling By Nerik Yakubov Introduction If you let a hot cup of coffee sit out in order to let it cool, then you are taking advantage of a phenomenon called heat transfer. Heat transfer takes place when any two objects of different temperatures are in contact with each other. In the case of the hot coffee, the two
