Question

A copper calorimeter weighing 57.5 gm. contains 60 gm of water at 12°C. 55 gm of iron nails at 100°c are dropped into the calorimeter and stirred rapidly. The final temperature
attained by the calorimeter and its contents is 20°C. Calculate the specific heat of iron. (sp. heat of copper = 0.4 J/gm°C. sp. heat of water = 4.2 J/gm°C).
