A piece of substance of specific heat capacity \(450\mathrm{Jkg}^{-1}\mathrm{k}^{1}\) falls through a vertical distance of \(20\mathrm{m}\) from rest. Calculate the rise in temperature of the substance on hitting the ground when all its energies are converted into heat. [\(g = 10\mathrm{ms}^{-2}\)]
