A heater supplies 36000 J to 0.20 kg of water and a metal container. Both warm by 30 ∘C30\ ^\circ\mathrm{C}30 ∘C. No energy reaches the surroundings. The container has mass 0.40 kg and water has specific heat capacity 4200 J kg−1 ∘C−14200\ \mathrm{J\,kg^{-1}\,{}^\circ C^{-1}}4200 Jkg−1∘C−1. What is the specific heat capacity of the metal?
