A steel ball of mass $0.1 kg$ falls freely from a height of $10 m$ and bounces to a height of $5.4m$ from the ground. If the dissipated energy in this process is absorbed by the ball, the rise in its temperature is ........... $^\circ \mathrm{C}$ (Specific heat of steel $ = 460\,Joule - k{g^{ - 1}}^\circ {C^{ - 1}},\;g = 10\,m{s^{ - 2}}$)
