Through the use of two temperature sensors, this item lets you study how the transfer of heat occurs between two bodies, solids or liquids, with different initial temperature. As in each balance phenomenon, the warmer body gives heat to the colder body until the cancellation of the thermal difference. The Law, states that the temperature of the warmer body varies over the time is exponentially decreasing, while the Law according to which the temperature of the colder body increases is exponentially increasing. It is possible to establish an analogy with the water balance phenomenon and electric balance.
