Neco 2022 Physics Question 50
Practice objective / multiple choice question 50 from the 2022 Neco Physics examination.
A \(200\ \text{g}\) piece of aluminium (\(c=0.900\ \text{J·g}^{-1}\text{K}^{-1}\)) at \(150^{\circ}\text{C}\) is placed into \(500\ \text{g}\) of water (\(c=4.18\ \text{J·g}^{-1}\text{K}^{-1}\)) initially at \(25^{\circ}\text{C}\). The calorimeter loses heat to the surroundings at a rate of \(12\ \text{J·min}^{-1}\) and the experiment lasts \(10\) minutes before equilibrium is reached. Assuming no phase change, find the final temperature of the mixture (in \(^\circ\text{C}\)).
