We know from the principle of calorimetry that if two objects of different temperature are put in thermal equilibrium, heat gets transferred from the hot object to the cold object. We also know that if the system is kept in thermal isolation and chemical reaction or other means of mass transfer are not allowed between the objects then heat given by the hot object equals heat taken by the cooler object. My question is can we find the time required for this heat transfer to happen given the masses of the objects, the temperatures of the objects, and their specific heat capacities? If not, what else do we need to know about the system and given that information how can we find the time required for the heat transfer to happen?
