Neco 2020 Physics Question 25
Practice objective / multiple choice question 25 from the 2020 Neco Physics examination.
A \(150\,\text{g}\) piece of ice at \(-10^{\circ}\text{C}\) is placed in a well‑insulated container with \(200\,\text{g}\) of water at \(25^{\circ}\text{C}\). No heat is lost to the surroundings. The specific heat capacities are \(c_{ice}=2.1\,\text{J\,g}^{-1}\text{K}^{-1}\) and \(c_{water}=4.18\,\text{J\,g}^{-1}\text{K}^{-1}\); the latent heat of fusion of ice is \(L_f=334\,\text{J\,g}^{-1}\). Determine the final temperature of the mixture and the mass of ice that melts.
