Neco Model Questions Vol1 2025 Physics Question 21
Practice objective / multiple choice question 21 from the 2025 Neco Model Questions Vol1 Physics examination.
A metal container of mass \(0.5\ \text{kg}\) and specific heat capacity \(0.9\ \text{kJ\,kg}^{-1}\text{K}^{-1}\) contains \(2.0\ \text{kg}\) of water at \(20^{\circ}\text{C}\). The container is placed on a stove that supplies \(500\ \text{kJ}\) of heat, but \(15\%\) of the supplied heat is lost to the surroundings. Assuming the container and the water reach the same final temperature, what is the final temperature of the water (to the nearest \(0.1^{\circ}\text{C}\))?
