| bomb calorimeter | An instrument which measures the heat released or absorbed during a chemical reaction. It is used for determining the potential energy of organic substances, including those in foods. It consists of a hollow steel container, lined with platinum and filled with pure oxygen, into which a weighed quantity of substance is placed and ignited with an electric fuse; the heat produced is absorbed by water surrounding the bomb and, from the rise in temperature, the calories liberated are calculated.

| Benedict-Roth calorimeter | <apparatus, physiology> A device employed to measure the amount of oxygen utilised in quiet breathing in the basal state for the estimation of the basal metabolic rate; the subject rebreathes oxygen through soda lime from a recording spirometer. (14 Aug 2000) |

| calorimeter | <radiobiology> In conventional fusion research, this name refers to any device used to measure power or energy in a laser or particle beam. (for example, for ICF or neutral beam heating or a magnetically-confined plasma.) (09 Oct 1997) |
| atomic bomb | <physics, radiobiology> A weapon with a large explosive power due to the sudden release of energy when the nuclei of heavy atoms such as plutonium-239 or uranium-235 are split. This fission is brought about by the bombardment of the fuel with neutrons, setting off a chain reaction. The bomb releases shock, blast, heat, light, and lethal radiation. The world's first atomic bomb was successfully tested by the United States on July 16, 1945. (13 Nov 1997) |
| bomb | 1. A great noise; a hollow sound. "A pillar of iron . . . Which if you had struck, would make . . . A great bomb in the chamber beneath." (Bacon) 2. A shell; especially. A spherical shell, like those fired from mortars. See Shell. 3. A bomb ketch. Bomb chest, a small ketch or vessel, very strongly built, on which mortars are mounted to be used in naval bombardments; called also mortar vessel. Bomb lance, a lance or harpoon with an explosive head, used in whale fishing. Volcanic bomb, a mass of lava of a spherical or pear shape. "I noticed volcanic bombs." Origin: F. Bombe bombshell, fr. L. Bombus a humming or buzzing noise, Gr. Source: Websters Dictionary (01 Mar 1998) |
| hydrogen bomb | <physics> An extremely powerful type of atomic bomb based on nuclear fusion. The atoms of heavy isotopes of hydrogen (deuterium and tritium) undergo fusion when subjected to the immense heat and pressure generated by the explosion of a nuclear fission unit in the bomb.

| bomb calorimeter |
an apparatus for measuring the potential energy of food, a weighed amount of the food being placed on a platinum dish inside a hollow steel container (bomb) filled with pure oxygen. The heat produced by its combustion is absorbed by a known quantity of water in which the container is immersed, permitting its measurement.
