Igcse Model Questions Vol1 2019 Physics Question 10
Practice objective / multiple choice question 10 from the 2019 Igcse Model Questions Vol1 Physics examination.
A 0.50 kg copper block (specific heat \(c_{Cu}=385\,\text{J kg}^{-1}\text{K}^{-1}\)) at \(150^{\circ}\text{C}\) is placed into 2.0 kg of water (specific heat \(c_{w}=4186\,\text{J kg}^{-1}\text{K}^{-1}\)) initially at \(20^{\circ}\text{C}\) inside an insulated container. The container loses heat to the surroundings at a constant rate of \(10\,\text{J s}^{-1}\). After 5 minutes the system reaches thermal equilibrium. Assuming no other losses, determine the final equilibrium temperature (in °C, to one decimal place) and the total heat transferred to the surroundings (in joules).
