Problem- A 2.5 g sample of French fries is placed in a calorimeter with 500.0 g of water at an initial temperature of 21°C. After combustion of the French fries the water has a temperature of 48°C. What is the caloric value (kcal/g) of the French fries? The heat capacity, CH2O, of the water is 1.00 cal/g °C. Remember that the heat, q, absorbed be a given mass, m, of water to raise its temperature T degrees is given by q = mCH2OT.
