A water-cooled plate removes energy from a 0.60 kg copper block at an average rate of 55 W for 3.5 min. The block is at 90 ∘C90\ ^\circ\mathrm{C}90 ∘C at the start and stays solid. The specific heat capacity of copper is 385 J kg−1 ∘C−1385\ \mathrm{J\,kg^{-1}\,{}^\circ C^{-1}}385 Jkg−1∘C−1. What is the temperature of the block at the end of the 3.5 min?
