Neco 2022 Physics Question 32
Practice objective / multiple choice question 32 from the 2022 Neco Physics examination.
A copper block of unknown mass \(m\) (in kg) is heated to \(150^{\circ}\text{C}\) and then placed into a calorimeter containing \(0.5\ \text{kg}\) of water at \(25^{\circ}\text{C}\). The calorimeter has a heat capacity of \(0.1\ \text{kJ\,K}^{-1}\). After thermal equilibrium the final temperature is \(35^{\circ}\text{C}\). Assuming no heat loss to the surroundings, determine the mass of the copper block (to three significant figures).
