Neco 2019 Physics Question 49
Practice objective / multiple choice question 49 from the 2019 Neco Physics examination.
200\ \text{g} of water at \(80^{\circ}\text{C}\) is mixed with 300\ \text{g} of water at \(25^{\circ}\text{C}\). No heat is lost to the surroundings.\n\n(a) Find the equilibrium temperature of the mixture (in \(^{\circ}\text{C}\)).\n(b) The mixture is then heated until its temperature rises by 15\% of the temperature difference between the mixture's temperature found in part (a) and the boiling point of water (100\(^{\circ}\)C). What is the new temperature (in \(^{\circ}\text{C}\), to one decimal place)?
