Neco 2017 Physics Question 36
Practice objective / multiple choice question 36 from the 2017 Neco Physics examination.
A copper block of mass 250 g is heated to an unknown temperature and then placed into 500 g of water at 20\(^\circ\)C contained in a calorimeter of heat capacity 60 J/\(^\circ\)C. After equilibrium the temperature of the system is 30\(^\circ\)C. Given the specific heat capacities of copper and water are 0.385 J/g\(^\circ\)C and 4.18 J/g\(^\circ\)C respectively, determine the initial temperature of the copper block (in \(^\circ\)C).
