Gce Model Questions Vol1 2018 Physics Question 33
Practice objective / multiple choice question 33 from the 2018 Gce Model Questions Vol1 Physics examination.
A 150 g block of copper (specific heat \(c_{\text{Cu}}=0.385\) J g\(^{-1}\) K\(^{-1}\)) at 200 °C is placed in thermal contact with 250 g of water (specific heat \(c_{\text{w}}=4.18\) J g\(^{-1}\) K\(^{-1}\)) initially at 20 °C. The insulated system reaches equilibrium, but 5 % of the heat lost by the copper is transferred to the container walls (which have negligible heat capacity) and does not reach the water. Determine the final equilibrium temperature of the water and the copper (in °C).
