Neco Model Questions Vol1 2018 Physics Question 1
Practice objective / multiple choice question 1 from the 2018 Neco Model Questions Vol1 Physics examination.
A 0.5 kg copper block (specific heat capacity \(c_{Cu}=385\ \text{J kg}^{-1}\text{K}^{-1}\)) at \(200^{\circ}\text{C}\) is placed into an insulated container that holds water initially at \(20^{\circ}\text{C}\). After thermal equilibrium the temperature of the system is \(30^{\circ}\text{C}\). If the specific heat capacity of water is \(c_{w}=4186\ \text{J kg}^{-1}\text{K}^{-1}\), determine the mass of water in the container.
