Question

A hot object is dropped into a thermally insulated container of water, and the object and water are then allowed to come to thermal equilibrium. The experiment is repeated twice, with different hot objects. All three objects have the same mass and initial temperature, and the mass and initial temperature of the waterare the same in the three experiments. For each of the experiments, Fig. 18-28 gives graphs of the temperatures T of the object and the water versus time t. Rank the graphs according to the specific heats of the objects, greatest first.

Explanation / Answer

Greater the specific heat less will be the change of temperature of object since C (delta T) = k now temperature of object changes least in figure c => specific heat of c>b>a
