Igcse Model Questions Vol1 2019 Physics Question 12
Practice objective / multiple choice question 12 from the 2019 Igcse Model Questions Vol1 Physics examination.
A 200 g block of copper (specific heat capacity \(c_{\text{Cu}}=0.385\) J·g\(^{-1}\)·K\(^{-1}\)) at \(150\) °C is placed into a well‑insulated container that holds 100 g of water at \(20\) °C (specific heat capacity \(c_{\text{w}}=4.18\) J·g\(^{-1}\)·K\(^{-1}\)). The container itself is initially at \(20\) °C. After the system reaches equilibrium the final temperature is \(30\) °C. It is known that 5 % of the heat released by the copper is lost to the surroundings. Determine the heat capacity of the container (in J·K\(^{-1}\)), assuming its temperature also rises to the final equilibrium temperature.
