Igcse Model Questions Vol1 2025 Physics Question 24
Practice objective / multiple choice question 24 from the 2025 Igcse Model Questions Vol1 Physics examination.
A \(300\ \text{g}\) iron block (specific heat capacity \(c_{\text{Fe}} = 0.45\ \text{J g}^{-1}\text{K}^{-1}\)) initially at \(200^{\circ}\text{C}\) is placed into an insulated container containing \(200\ \text{g}\) of water (specific heat capacity \(c_{\text{water}} = 4.18\ \text{J g}^{-1}\text{K}^{-1}\)) initially at \(20^{\circ}\text{C}\). After the system reaches thermal equilibrium the temperature is \(40^{\circ}\text{C}\). (i) Calculate the heat lost by the iron block. (ii) What percentage of this heat is transferred to the water? (Give your answer to one decimal place.)
