A calorimeter is a scientific instrument used to measure the heat generated or absorbed in a chemical reaction or physical process. We owe the invention of this device to an observation made just before the turn of the nineteenth century by the...

A calorimeter is a chamber, entirely closed from the outside world, in which one can house an animal and record its body heat. It is used to determine the METABOLIC RATE of small animals—calorimeters for use by large animals (including humans)...

Device for measuring heat produced during a mechanical, electrical, or chemical reaction and for calculating the heat capacity of materials. A common design, known as a bomb calorimeter, consists of a reaction chamber surrounded by a liquid that...

A scientific instrument used to measure differences in heat energy during the course of a chemical reaction or process such as combustion. The differences are usually expressed in CALORIES per unit mass of...

A calorimeter is a device used for calorimetry, the science of measuring the heat of chemical reactions or physical changes as well as heat capacity. The word calorimeter is derived from the Latin word calor, meaning heat. Differential scanning...
