Igcse Model Questions Vol1 2023 Physics Question 13
Practice objective / multiple choice question 13 from the 2023 Igcse Model Questions Vol1 Physics examination.
A \(250\ \text{g}\) copper block (specific heat \(c_{Cu}=0.385\ \text{J g}^{-1}\text{K}^{-1}\)) initially at \(150\ ^\circ\text{C}\) is placed into \(100\ \text{g}\) of water (specific heat \(c_{w}=4.18\ \text{J g}^{-1}\text{K}^{-1}\)) initially at \(20\ ^\circ\text{C}\) in an insulated container. After equilibrium the temperature of the system is \(30\ ^\circ\text{C}\). What percentage of the heat lost by the copper is transferred to the water? Give your answer to one decimal place.
