Physics
A metal piece of mass 420 g present at 80°C is dropped in 80 g of water present at 20°C in a calorimeter of mass 84 g. If the final temperature of the mixture is 30°C, then calculate the specific heat capacity of the metal piece.
[Specific heat capacity of water = 4.2 Jg-1 °C-1, Specific heat capacity of the calorimeter = 200 Jkg-1 °C-1]
