Gce Model Questions Vol1 2022 Physics Question 15
Practice objective / multiple choice question 15 from the 2022 Gce Model Questions Vol1 Physics examination.
In an insulated container, \(200\ \text{g}\) of water at \(80^{\circ}\text{C}\) is mixed with \(300\ \text{g}\) of water at \(20^{\circ}\text{C}\). After the mixture reaches thermal equilibrium, \(50\ \text{g}\) of ice at \(0^{\circ}\text{C}\) is added and melts completely. Assuming no heat loss to the surroundings and using \(c_{\text{water}} = 4186\ \text{J kg}^{-1}\text{K}^{-1}\) and the latent heat of fusion of ice \(L_{f} = 334\ \text{kJ kg}^{-1}\), determine the final temperature of the system. Give your answer in degrees Celsius (to the nearest whole number).
