A piece of iron of mass 100 g is kept inside a furnace for a long time and then put in a calorimeter of water equivalent 10 g containing 240 g of water at 20∘C. The mixture attains an equilibrium teperature of 60∘C. Find the temperature of the furnace. Specific heat capacity of iron =470 H kg−1∘C−1. |
