Neco Model Questions Vol1 2025 Chemistry Question 1
Practice objective / multiple choice question 1 from the 2025 Neco Model Questions Vol1 Chemistry examination.
A 150 g sample of water at \(25^{\circ}\text{C}\) is heated in a calorimeter by a heater delivering \(500\ \text{W}\) for \(10\) minutes. No heat is lost to the surroundings. The specific heat capacity of water is \(4.18\ \text{J g}^{-1}\text{°C}^{-1}\) and the latent heat of vaporisation is \(2260\ \text{J g}^{-1}\). Determine the final state of the system (liquid water only, a mixture of liquid water and steam, or steam only) and the temperature of the system after heating.
