Neco 2019 Physics Question 44
Practice objective / multiple choice question 44 from the 2019 Neco Physics examination.
A 200\,g sample of water at \(80^{\circ}\text{C}\) is placed in a container that loses heat to the surroundings (\(25^{\circ}\text{C}\)) at a rate \(P = k\,(T-25)\) with \(k = 0.05\,\text{W\,^{\circ}C^{-1}}\). The specific heat capacity of water is \(c = 4.18\,\text{J\,g^{-1}\,^{\circ}C^{-1}}\). Assuming no phase change, find the temperature of the water after \(10\) minutes.
