2 spheres have diameters in ratio 1:2 specific heats in 1:3 and densities in 2:1. Find ratio of thermal capacities

best_answer

The thermal capacities = mass*  specific heat

vol of sphere = 4/3 (pi)R^{3}

ratio of T_{c1}\mid T_{c2} = (d1/d2)^{3}*(\rho _{1}/\rho_{2})*(S_{1}/S_{2})

                                  =  (1/2)^{3}*(1/2)*(1/3)

                                   =1/12
