Neco Model Questions Vol1 2020 Physics Question 9
Practice objective / multiple choice question 9 from the 2020 Neco Model Questions Vol1 Physics examination.
A 2.0 kg block of copper (specific heat capacity unknown) at \(150^{\circ}\)C is placed into 1.0 kg of water (specific heat capacity \(4186\) J kg\(^{-1}\) K\(^{-1}\)) initially at \(20^{\circ}\)C in an insulated container. After the system reaches equilibrium at \(40^{\circ}\)C, it is found that \(5.0\) kJ of heat has been lost to the surroundings. Determine the specific heat capacity of the copper in J kg\(^{-1}\) K\(^{-1}\).
