Next place about 250 mL of tap water into a 400 mL beaker. Add 4-5 boiling chips into the tap water to prevent bumping. Bring the tap water to a gentle boil using a hot plate.Calorimetry is the science of measuring heat flow. Heat is defined as thermal energy flowing from an object at a higher temperature to one at a lower temperature. For example, if you drop a coin into a cup with hot water, the temperature of the coin will go up until it is at the same temperature as the boiling water.
