define thermonuclear reaction


Relating to or characterized by the use of weapons that employ nuclear fusion, especially as distinguished from those that employ only nuclear fission. Interaction time is critical for defining the reaction mechanism. A nuclear weapon is commonly defined as a device, which uses a nuclear reaction for destructive means. Critical mass: The smallest mass of fissile material that will support a self-sustaining chain reaction under specified conditions. Thermonuclear reactions occur in the Suns core, a discharged energy of them are brought to the outer layers giving rise to the complex structure and dynamics of these layers: a convective zone, photosphere, chromospheres, corona, and solar wind. English Wikipedia - The Free Encyclopedia. Login In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus. Examples. Definition of thermonuclear reaction is ( ). A fusion reaction releases about four times more energy per unit mass than does a fission reaction.

Services means those functional services ancillary to the supply of the goods, such as transportation and any other incidental services, such as installation, commissioning, provision of technical Because of those reactions, the temperature of the Sun's core is at the level of 10 7 K. Density of the Sun's core is approximately 100 times higher than that of water. The nuclear weapon, code named Trinity, yielded an explosion which was equivalent to 20 kilotons of Trinitrotoluene (TNT). To simplify, the products formed in nuclear fission and nuclear fusion generally have a lower mass than the reactants. The Sun consists approximately of 80% hydrogen and 20% helium; other elements constitute The neutron absorption reaction is the most important type of reactions that take place in a nuclear reactor.The absorption reactions are reactions where the neutron is completely absorbed, and the compound nucleus is formed.This is a very important feature because the mode of decay of such a compound nucleus does not depend on how the compound nucleus was formed. The purpose of the weapon is to contaminate the area around the dispersal agent/conventional explosion with radioactive material, serving primarily as an area denial device against civilians. Relating to or derived from the fusion of atomic nuclei at high temperatures: thermonuclear reactions.

Subjects: Science and technology Environmental Science. Thermonuclear as a means Relating to the fusion of atomic nuclei at high temperatures or to the energy produced in this way.. Thermonuclear reactions. Nuclear bombardment reactions are nuclear reaction in which a nucleus is bombarded or struck by another nucleus or nuclear particle. Translate From English into Sinhala. A fission reaction at a nuclear power plant provides enough energy to give electricity to large cities. This is why conservation of mass seems to hold in reactions. Spending on education? Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. These used thermonuclear fuel around or inside the atomic core to greatly increase the power of the weapon. The Lawson criterion is a key concept in the pursuit of fusion energy, relating the fuel density n, pulse duration or energy confinement time E, and fuel temperature T to the energy gain Q of a fusion plasma. English-Sinhala-English Multilingual Dictionary. Nuclear pollution, also called Radioactive contamination, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable.

Inertial confinement fusion is generated by compressing a millimetre-sized capsule containing a thermonuclear fuel combination of deuterium and tritium. The capsule is heated by x rays produced by high-power lasers, converting it to plasma. What does thermonuclear reaction mean? Define the following terms: (a)Atomic number and (b) mass number. The Kentucky Wildcats cap off another unbelievable season, reaching ten wins for the second time in four seasons, beating the Iowa Hawkeyes, 20-17. Kentucky struck first and controlled the first half, leading 13-3 at the break with two interceptions on Spencer Petras. For example, combustion of one mole methane loses 9.9 x 10-9 grams. An important example of nuclear fission is the splitting of the uranium-235 nucleus when it is bombarded with neutrons. Nuclear Reaction. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy. Moreover, for the An 602, several layers were made, which were set on fire in turn (which is why Sakharov called the charge a puff). The nuclear reaction can be written as: 25 12Mg + 4 2He 1 1H + A ZX 12 25 Mg + 2 4 He 1 1 H + Z A X. where A is the mass number and Z is the atomic number of the new nuclide, X.
