Neco 2017 Physics Question 5
Practice objective / multiple choice question 5 from the 2017 Neco Physics examination.
A \(200\ \text{g}\) block of ice at \(-10^{\circ}\text{C}\) is placed in \(500\ \text{g}\) of water at \(30^{\circ}\text{C}\) in an insulated container. The specific heat capacities are \(c_{\text{ice}} = 2.1\ \text{J g}^{-1}\text{K}^{-1}\) and \(c_{\text{water}} = 4.18\ \text{J g}^{-1}\text{K}^{-1}\). The latent heat of fusion of ice is \(L_f = 334\ \text{J g}^{-1}\). Determine the final temperature of the system and the mass of ice that melts (in grams, to three significant figures).
