1. an instrument used to measure the amount of heat produced or absorbed in a chemical reaction or physical change
Usage: scientific; physics; chemistry

Examples

• The chemistry students used a calorimeter to measure the heat released during combustion.
• Scientists calibrated the calorimeter before conducting the experiment.
• The calorimeter showed that the reaction was highly exothermic.
• Food energy content is often determined using a bomb calorimeter.
• The laboratory’s calorimeter could detect very small temperature changes.
• Researchers placed the sample inside the calorimeter’s insulated chamber.
