Suppose the calorimeter for this experiment had been made of a heat-conducting material (such as metal) rather than plastic foam, so that the portion of heat energy lost to the calorimeter itself was larger and could not be ignored. Would the temperature changes experience when mixing the acid with the base have been larger or smaller? Explain
