Neco Model Questions Vol1 2017 Physics Question 19
Practice objective / multiple choice question 19 from the 2017 Neco Model Questions Vol1 Physics examination.
A metal block of mass \(2.0\;\text{kg}\) and specific heat capacity \(0.45\;\text{kJ·kg}^{-1}\text{K}^{-1}\) is initially at \(150^{\circ}\text{C}\). It is placed into an insulated container that holds \(1.5\;\text{kg}\) of water at \(20^{\circ}\text{C}\). The container itself has a mass of \(0.5\;\text{kg}\) and a specific heat capacity of \(0.90\;\text{kJ·kg}^{-1}\text{K}^{-1}\). Assuming no heat is lost to the surroundings, calculate the final equilibrium temperature of the system in degrees Celsius, correct to one decimal place.
