Use the specific heat capacity that you calculated for granite to determine how many grams of granite at the initial temperature of 80 °c must mix with 3,000 g of water at the initial temperature of 20 °c to result in a final system temperature of 20. 45 °c. (hint: start by calculating how much heat energy is needed to change the water’s temperature by 0. 45 °c). Show your work. Use the gizmo to check your answer.
