PASSAGE
A 0.200 kg0.200\ \mathrm{kg} aluminum block at 80.0 ∘C80.0\ ^\circ\mathrm{C} is placed in 0.300 kg0.300\ \mathrm{kg} of water at 20.0 ∘C20.0\ ^\circ\mathrm{C} inside an insulated container. The specific heat capacities of aluminum and water are 900 J/(kg⋅∘C)900\ \mathrm{J/(kg\cdot ^\circ C)} and 4200 J/(kg⋅∘C)4200\ \mathrm{J/(kg\cdot ^\circ C)}, respectively.
