Neco Model Questions Vol1 2025 Physics Question 35
Practice objective / multiple choice question 35 from the 2025 Neco Model Questions Vol1 Physics examination.
A \(150\ \text{g}\) block of ice at \(-5^{\circ}\text{C}\) is placed in a well‑insulated container with \(200\ \text{g}\) of water at \(30^{\circ}\text{C}\). No heat is lost to the surroundings. The specific heat capacities are \(c_{\text{ice}} = 2.1\ \text{J g}^{-1}\!\text{°C}^{-1}\) and \(c_{\text{water}} = 4.18\ \text{J g}^{-1}\!\text{°C}^{-1}\); the latent heat of fusion of ice is \(L_f = 334\ \text{J g}^{-1}\). Determine the final state of the system (mass of ice and water) and the final temperature.
