Igcse Model Questions Vol1 2022 Physics Question 16
Practice objective / multiple choice question 16 from the 2022 Igcse Model Questions Vol1 Physics examination.
A calorimeter of heat capacity \(50\ \text{J/°C}\) contains \(150\ \text{g}\) of water at \(20^{\circ}\text{C}\). An unknown mass of water at \(80^{\circ}\text{C}\) is added, and the final equilibrium temperature of the mixture is \(40^{\circ}\text{C}\). Assuming the specific heat capacity of water is \(4.18\ \text{J/g°C}\), calculate the mass of the hot water added (in grams, correct to the nearest gram).
