A 30.0 g piece of metal at 10∘C10^\circ\text{C} is placed into 120.0 g of water at 40∘C40^\circ\text{C} in an insulated container. The specific heats are cmetal=0.80 J g−1 ⁣ ⁣⋅ ⁣∘C−1c_{\text{metal}}=0.80\ \text{J g}^{-1}\!\!\cdot\!^\circ\text{C}^{-1} and cwater=4.18 J g−1 ⁣ ⁣⋅ ⁣∘C−1c_{\text{water}}=4.18\ \text{J g}^{-1}\!\!\cdot\!^\circ\text{C}^{-1}. Heat lost equals heat gained. Which statement is correct about the signs of qq for each substance (taking q>0q>0 as heat gained by the substance)?
