149456 The total energy radiated from a black body source is collected for $1 \mathrm{~min}$ and is used to heat a quantity of water. The temperature of water is found to increase from $20^{\circ} \mathrm{C}$ to $20.5^{\circ} \mathrm{C}$. If the absolute temperature of the black body is doubled and the experiment is repeated with the same quantity of water at $20^{\circ} \mathrm{C}$, the temperature of water will be :
