In an experiment to measure the temperature of the flame of a Bunsen burner, a lump of copper of mass 0.12 kg is heated on the flame for a long time. The copper then is quickly transferred into a beaker of negligible heat capacity containing 0.84 kg of water and the temperature of the water rose from 15 °C to 35 °C. Calculate the temperature of the flame.
[Given : Specific heat capacity of copper = 0.4 J g-1 °C-1, Specific heat capacity of water = 4.2 J g-1 °C-1]
