Neco Model Questions Vol1 2017 Physics Question 10
Practice objective / multiple choice question 10 from the 2017 Neco Model Questions Vol1 Physics examination.
A \(150\ \text{g}\) piece of ice at \(-10^{\circ}\text{C}\) is placed in a \(200\ \text{g}\) sample of water at \(40^{\circ}\text{C}\). The calorimeter is assumed to have negligible heat capacity. 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 mass of ice that melts, giving your answer to the nearest gram.
