PDF Thermochemistry Problems - Laney College Laney College [11] For this problem, we do not know the temperature change that either the brick or the water is undergoing. We do know that q water = -q bricks. First, find the heat capacity, not the specific heat of 1000 gal of water. Then, use that number to find the number of bricks. C = 1.0 X 103 gal X 4 qt 1 gal X 1 L 1.0567 qt X 1000 mL L X 1.00 g 1 ... PDF Answers, Thermochemistry Practice Problems 2 Answers, Thermochemistry Practice Problems 2 1 6.
