Definition

1. Noun:
   • A measuring instrument that determines quantities of heat: A device used in physics and chemistry to measure the amount of heat absorbed or released in a chemical reaction, physical change, or heat capacity.

Usage Examples

• Noun:
  • The scientist used a calorimeter to measure the heat of combustion of the fuel.
  • In the laboratory, we learned how to operate a bomb calorimeter to find the energy content of food samples.

Advanced Usage

• "Bomb calorimeter": A specific type of calorimeter used for measuring the heat of combustion of a substance, typically involving a sealed, high-pressure container (the "bomb").
  • The bomb calorimeter provided precise data on the fuel's energy value.
• "Differential scanning calorimeter (DSC)": An advanced instrument that measures the difference in heat flow between a sample and a reference material as a function of temperature.
  • The polymer's glass transition temperature was analyzed using a differential scanning calorimeter.

Variants and Related Words

• Calorimetric (adj): Relating to the measurement of heat.
  • The calorimetric data confirmed the theory.
• Calorimetry (n): The science or process of measuring heat changes.
  • The experiment involved the principles of calorimetry.

Synonyms

• Heat measurer: (Descriptive synonym) An instrument for measuring heat.
• Thermal analysis instrument: (Technical synonym) A device for studying material properties through heat flow.

Related Phrases

• "To place in a calorimeter": The action of putting a substance into the device for measurement.
  • The compound was placed in a calorimeter to determine its specific heat capacity.
• "Calorimeter reading": The value or data obtained from the instrument.
  • The calorimeter reading indicated an exothermic reaction.
