involved when two incompressible substances are mixed together. 12 experiments were performed‚ 10 involving the combination of a measured amount of hot and cold water and 2 involving the combination of ice and liquid water‚ the majority of these experiments were performed three times. The average variance in final temperature for each experiment was less than 10 percent providing proof of repeatability. Equipment used during the experiment included a gram scale‚ thermocouple‚ Styrofoam cup‚ glass beakers
