Which statement defines calorimetry? the conservation of energy a unit of energy that is used when calculating energy exchange a device that is used to measure the heat that is gained or lost during a chemical change the measurement of energy that is given off or absorbed in a physical or chemical process

Answer: the measurement of energy that is given off or absorbed in a physical or chemical process

Explanation: Calorimetry is the process of measuring the amount of heat released or absorbed during a chemical reaction.

It can be found whether a reaction is exothermic or endothermic by knowing the change in heat. This is done by the use of device called calorimeter.

Exothermic reactions are accompanied by release of heat whereas endothermic reactions are accompanied by absorption of heat. Thus by knowing the temperature changes, we get to know whether the heat has been released or absorbed.

Calorimeter is used measure energy changes in a chemical or a physical process. Energy can be in the form of electrical, heat or light energy. Changes in heat energy are generally measured in calorimeter. The mass of water or solution contained in the calorimeter, temperature changes taking place in the calorimeter and the specific heat of water (or solution) is used to measure the amount of heat absorbed or given off by the water (or solution) during the chemical change or physical change that takes place in the calorimeter.

Therefore, the correct option will be,

D) measurement of energy that is given off or absorbed in a physical or chemical process
