A 588 g chunk of iron is heated to 97.5°C. Then it is immersed in 247 mL of water originally at 20.7°C.
When thermal equilibrium has been reached, the water and the iron are both at 36.2°C. Calculate the specific heat of the iron. Assume no heat loss to the calorimeter and the density of water is 1.00g/mL. The specific heat capacity of water is 4.184 J/g·°C.
