Neco Model Questions Vol1 2025 Physics Question 40
Practice objective / multiple choice question 40 from the 2025 Neco Model Questions Vol1 Physics examination.
A mixture is prepared by combining \(250\ \text{g}\) of water at \(80^{\circ}\text{C}\) with \(150\ \text{g}\) of ethanol (specific heat capacity \(2.44\ \text{J·g}^{-1}\text{K}^{-1}\)) at \(20^{\circ}\text{C}\) in an insulated container. During mixing, \(20\ \text{g}\) of ice at \(0^{\circ}\text{C}\) melts completely. Assuming no heat loss to the surroundings, determine the final equilibrium temperature of the mixture in degrees Celsius (rounded to the nearest degree).
