bomb calorimeter

Physics

An apparatus used for measuring heats of combustion (e.g. calorific values of fuels and foods). It consists of a strong container in which the sample is sealed with excess oxygen and ignited electrically. The heat of combustion at constant volume can be calculated from the resulting rise in temperature.

Chemistry

An apparatus used for measuring heats of combustion (e.g. calorific values of fuels and foods). It consists of a strong container in which the sample is sealed with excess oxygen and ignited electrically. The heat of combustion at constant volume can be calculated from the resulting rise in temperature.

Chemical Engineering

An instrument used to determine the heat of combustion of a substance. It typically consists of a steel chamber with a non-oxidizable material on the inside, with a tight-fitting screw lid. A known mass of sample of material is burnt in a platinum cup. Insulated platinum leads allow an electric current to be passed through a thin wire to ignite the material. The air in the chamber is replaced with pure oxygen, which is allowed to reach a pressure of around 20 atmospheres. The calorimeter is surrounded by water and once the combustion has begun, the rise in temperature recorded from which the heat of combustion is determined.

Biology

An apparatus used for measuring heats of combustion. It consists of a strong container in which the sample is sealed with excess oxygen and ignited electrically. The heat of combustion at constant volume can be calculated from the resulting rise in temperature. The apparatus is used to calculate the calorific values of foods and the energy content of a sample of biomass, required for constructing a pyramid of energy.
