Two metal spheres with same temperature are immersed in the same excess fluid. the fluid has constant temperature. the radius of a is double that of b, and the time of b required for the central point temperature to approach particular temperature is double that of a. calculate the relation between the thermal diffusivity of a and that of b.

It will appear as o2(g) as a reactant
