Neco Model Questions Vol1 2017 Physics Question 1
Practice objective / multiple choice question 1 from the 2017 Neco Model Questions Vol1 Physics examination.
A copper block is heated to \(150^{\circ}\text{C}\) and then placed in an insulated container containing \(200\ \text{g}\) of water at \(20^{\circ}\text{C}\). After equilibrium the temperature of the system is \(30^{\circ}\text{C}\). The specific heat capacity of copper is \(0.385\ \text{J g}^{-1}\!^{\circ}\text{C}^{-1}\). Assuming no heat loss to the surroundings, determine the mass of the copper block (in grams) to the nearest gram.
