Neco Model Questions Vol1 2024 Physics Question 18
Practice objective / multiple choice question 18 from the 2024 Neco Model Questions Vol1 Physics examination.
A 150 g metal block (specific heat \(c_m = 0.385\,\text{J g}^{-1}\text{°C}^{-1}\)) at \(120^{\circ}\text{C}\) is placed into a calorimeter containing 200 g of water (specific heat \(c_w = 4.18\,\text{J g}^{-1}\text{°C}^{-1}\)) initially at \(25^{\circ}\text{C}\). After thermal equilibrium the temperature of the system is \(30^{\circ}\text{C}\). If the calorimeter itself has an unknown heat capacity \(C_{\text{cal}}\) (in J/°C), determine \(C_{\text{cal}}\).
