seventu grams of a piece of iron at 95 degree celsius is dropped into a copper calorimeter containing 150 grams of water at 20 degree celsius. the mass of copper calorimeter is 90 grams the final temperature of the mixture is 25 degree celsius. determine the specific heat of iron.

Answer 1

The sum of heats gained will be zero.

Heat gained is defined as mass*specheat*(tf-ti)

HeatgainedIron+HeatgainedCu+heatgainedwater=0

70*Ciron*(25-95)+150*Cwater*(25-20)+90*ccopper*(25-20)=0

solve for ciron.
