An aneroid calorimeter is a device used to measure the heat of combustion of a substance. It is a type of calorimeter that uses a vacuum chamber to hold the sample and a spring-loaded aneroid barometer to measure the pressure changes that occur during combustion. This article will provide a detailed definition of aneroid calorimeter, its origin, meaning in different dictionaries, associations, synonyms, antonyms, and example sentences.
Definitions
An aneroid calorimeter is a type of calorimeter that measures the heat of combustion of a substance. It uses a vacuum chamber to hold the sample and a spring-loaded aneroid barometer to measure the pressure changes that occur during combustion.
Origin
The aneroid calorimeter was first developed by French chemist Pierre-Eugène-Marcellin Berthelot in the late 19th century. Berthelot was interested in studying the thermodynamics of chemical reactions and developed the aneroid calorimeter to measure the heat of combustion of various substances.
Meaning in different dictionaries
The meaning of aneroid calorimeter in different dictionaries is as follows:
- Merriam-Webster: a calorimeter in which the heat of combustion of a substance is measured by the expansion of a vacuum chamber and the pressure change in an aneroid barometer.
- Oxford English Dictionary: a calorimeter in which the heat of combustion of a substance is measured by the expansion of a vacuum chamber and the pressure change in an aneroid barometer.
- Cambridge Dictionary: a device used to measure the heat of combustion of a substance, using a vacuum chamber and a spring-loaded aneroid barometer to measure pressure changes during combustion.
Associations
The aneroid calorimeter is associated with the study of thermodynamics, chemical reactions, and combustion. It is commonly used in chemistry laboratories to measure the heat of combustion of various substances.
Synonyms
Synonyms of aneroid calorimeter include combustion calorimeter, Berthelot calorimeter, and bomb calorimeter.
Antonyms
Antonyms of aneroid calorimeter are not applicable as it is a specific device and has no opposite.
The same root words
The word “aneroid” in aneroid calorimeter refers to the use of a spring-loaded aneroid barometer to measure pressure changes. The word “calorimeter” refers to a device used to measure the heat of a substance.
