A 10 kW drilling machine is used to drill a bore in a small aluminium block of mass 8 kg. Find the rise in temperature of the block in `2.5` minutes, assuming `50%` power is used up in heating the machine itself or lost to the surropundings.
(Specific heat of aluminium `= 0.91 J g^(-1).^(@)C^(-1)`)
