Calorimetry
The nutritional information on this packaging shows that each serving has 10 calories within it. This value was determined using a calorimeter.
A A machine used to measure the energy involved in a chemical process. is a machine used in the process of Measuring the amount of heat given out or taken in by a process, such as the combustion of a fuel.. Small samples of material are placed in the machine which burns them. The energy given off when the material burns is measured.
Calorimeters are often used in the food industry to measure the energy in food. This value is given in The unit of work or energy, written as J. or calories in the nutritional information panel on the food packaging.
The simplest calorimeter can be made by arranging a beaker of water above a burning sample. The change in temperature of the water is a direct measure of the energy held within the sample.
