A drilling machine is used to drill a hole in a 10 kg metal block. Power of the drilling machine is 1 KW and it is used for 5 minutes. If 40% of the work done by the drilling machine is converted into heat in the metal block, the rise in its temperature is (Specific heat- 0.12 cal gm^(-1).^(@)C^(-1) and J=4.2 J/Cal)
