Two circular discs A and B with equal radii are blackened. They are heated to some temperature and are cooled under identical conditions. What inference do you draw from their cooling curves?

According to Newton’s law of cooling, rate of cooling is given by

Where c is specific heat of material.
or
rate of cooling varies inversely as specific heat. From the graph, for A rate of cooling is larger. Therefore, specific heat of A is smaller.
Where c is specific heat of material.
