Neco Model Questions Vol1 2021 Physics Question 20
Practice objective / multiple choice question 20 from the 2021 Neco Model Questions Vol1 Physics examination.
\(150\ \text{g}\) of water at \(80^{\circ}\text{C}\) is mixed with a \(200\ \text{g}\) aluminum block at \(25^{\circ}\text{C}\). The specific heat capacities are \(c_{\text{water}} = 4.18\ \text{J g}^{-1}\text{K}^{-1}\) and \(c_{\text{Al}} = 0.900\ \text{J g}^{-1}\text{K}^{-1}\). Assuming no heat loss to the surroundings, determine the final equilibrium temperature of the mixture (in \(^\circ\text{C}\)).
