Gce Model Questions Vol1 2024 Physics Question 35
Practice objective / multiple choice question 35 from the 2024 Gce Model Questions Vol1 Physics examination.
A well‑insulated container holds \(0.5\ \text{kg}\) of water at \(80^{\circ}\text{C}\) and \(0.3\ \text{kg}\) of oil (specific heat capacity \(c_{o}=2.0\ \text{kJ kg}^{-1}\text{K}^{-1}\)) at \(20^{\circ}\text{C}\). The container loses heat to the surroundings at a rate proportional to the temperature difference between the mixture and the ambient temperature of \(25^{\circ}\text{C}\), with proportionality constant \(k=10\ \text{W K}^{-1}\). Assuming the mixture behaves as a single body with total heat capacity equal to the sum of the individual heat capacities, find the temperature of the mixture after \(5\) minutes.
