Igcse Model Questions Vol1 2025 Physics Question 10
Practice objective / multiple choice question 10 from the 2025 Igcse Model Questions Vol1 Physics examination.
A \(200\ \text{g}\) piece of aluminium (specific heat capacity \(c_{\text{Al}} = 0.900\ \text{J g}^{-1}\text{K}^{-1}\)) at \(150^{\circ}\text{C}\) is placed into \(300\ \text{g}\) of water (specific heat capacity \(c_{\text{w}} = 4.18\ \text{J g}^{-1}\text{K}^{-1}\)) at \(25^{\circ}\text{C}\) in an insulated container. After reaching thermal equilibrium, the mixture cools to \(30^{\circ}\text{C}\) losing heat to the surroundings. Assuming no phase change, calculate the total heat lost to the surroundings during the cooling (in joules, to three significant figures).
