Neco Model Questions Vol1 2020 Chemistry Question 10
Practice objective / multiple choice question 10 from the 2020 Neco Model Questions Vol1 Chemistry examination.
A 100 g block of ice at \(-10^{\circ}\text{C}\) is placed in a well‑insulated container with 200 g of water at \(80^{\circ}\text{C}\). The specific heat capacities are \(c_{\text{ice}} = 2.1\ \text{J g}^{-1}\text{K}^{-1}\), \(c_{\text{water}} = 4.18\ \text{J g}^{-1}\text{K}^{-1}\), and the latent heat of fusion of ice is \(L_f = 334\ \text{J g}^{-1}\). Determine the final state of the system and the equilibrium temperature (to two significant figures).
