The total energy radiated from a black body source is collected for one minute and is used to heat a quantity of water. The temperature of water is found to increase form \[{{20}^{o}}C\] to \[{{20.5}^{o}}C\]. If the absolute temperature of the black body is doubled and the experiment is repeated with the same quantity of water at \[{{20}^{o}}C\], the temperature of water will be [UPSEAT 2004]

• A.            \[{{21}^{o}}C\]                    
• B.            \[{{22}^{o}}C\]
• C.            \[{{24}^{o}}C\]                    
• D.            \[{{28}^{o}}C\]
