Neco 2017 Physics Question 24
Practice objective / multiple choice question 24 from the 2017 Neco Physics examination.
A 150\,g piece of aluminum (specific heat 0.900\,J·g^{-1}·K^{-1}) at 80\,°C is placed into 250\,g of water (specific heat 4.18\,J·g^{-1}·K^{-1}) at 20\,°C inside an insulated container. During the 10‑minute process the container loses heat to the surroundings at a constant rate of 12\,J·min^{-1}. Assuming thermal equilibrium is reached after the 10\,minutes, determine the final temperature of the mixture (in \(^\circ\)C, to two decimal places).
