Neco Model Questions Vol1 2022 Physics Question 17
Practice objective / multiple choice question 17 from the 2022 Neco Model Questions Vol1 Physics examination.
A metal rod of mass \(2.0\ \text{kg}\) and specific heat capacity \(0.45\ \text{kJ\,kg}^{-1}\text{K}^{-1}\) is heated from \(20^{\circ}\text{C}\) to \(80^{\circ}\text{C}\). It is then placed into \(5.0\ \text{kg}\) of water initially at \(25^{\circ}\text{C}\) (specific heat \(4.18\ \text{kJ\,kg}^{-1}\text{K}^{-1}\)). Assuming no heat loss to the surroundings, determine the final equilibrium temperature of the system (to one decimal place).
