In order to design an experiment to model exothermic reactions, a student places various levels of calcium chloride (0 grams, 2 grams, 4 grams, 6 grams, 8 grams, and 10 grams) into beakers with 100 ml of water. The temperature of the water taken before and after the calcium chloride is placed in the solution is recorded. What evidence would support the student's claim that the concentration of calcium chloride is directly related to the amount of energy in the reaction?
