31Specific heat capacity — Specific heat capacity, also known simply as specific heat, is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval. The term originated primarily through the work …
32Elastic collision — [ black body radiation (not shown) doesn’t escape a system, atoms in thermal agitation undergo essentially elastic collisions. On average, two atoms rebound from each other with the same kinetic energy as before a collision. Here, room… …
33Inelastic collision — An inelastic collision is a collision in which kinetic energy is not conserved (see elastic collision).In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect.The molecules …
34Detailed balance — The principle of detailed balance is formulated for kinetic systems which are decomposed into elementary processes (collisions, or steps, or elementary reactions): At equilibrium, each elementary process should be equilibrated by its reverse… …
35Neutron moderator — Currently operating nuclear power reactors by moderator Moderator Reactors Design Country none (fast) 1 BN 600 Russia (1) graphite 29 AGR, Magnox, RBMK United Kingdom (18), Russia (11) heavy water 29 CANDU …
36Rate equation — The rate law or rate equation for a chemical reaction is an equation that links the reaction rate with concentrations or pressures of reactants and constant parameters (normally rate coefficients and partial reaction orders).[1] To determine the… …
37Rocket — This article is about vehicles powered by rocket engines. For other uses, see Rocket (disambiguation). A Soyuz U, at Baikonur Site 1/5 A rocket is a missile, spacecraft, aircraft or other vehicle which obtains thrust from a rocket engi …
38Ultracold neutrons — (UCN) are free neutrons which can be stored in traps made from certain materials. The storage is based on the reflection of UCN by such materials under any angle of incidence. Properties The reflection is caused by the coherent strong interaction …
39electromagnetic radiation — Physics. radiation consisting of electromagnetic waves, including radio waves, infrared, visible light, ultraviolet, x rays, and gamma rays. [1950 55] * * * Energy propagated through free space or through a material medium in the form of… …
40Mean free path — In physics, the mean free path is the average distance covered by a moving particle (such as an atom, a molecule, a photon) between successive impacts (collisions) [1] which modify its direction or energy or other particle properties. Contents 1… …
