Neco 2017 Physics Question 45
Practice objective / multiple choice question 45 from the 2017 Neco Physics examination.
200 g of water at \(80^{\circ}\text{C}\) is mixed with 300 g of water at \(25^{\circ}\text{C}\) in an insulated container. (a) Find the final equilibrium temperature of the mixture. (b) Using the mixture at the final temperature, determine the maximum mass of ice at \(0^{\circ}\text{C}\) that can be melted. (Take the specific heat capacity of water as \(4.18\ \text{J g}^{-1}\text{K}^{-1}\) and the latent heat of fusion of ice as \(334\ \text{J g}^{-1}\).)
