The neutron detection temperature, also called the neutron energy, indicates a free neutron 's kinetic energy, usually given in electron volts. The term temperature is used, since hot, thermal and cold neutrons are moderated in a medium with a certain temperature.pithermal neutrons have energies between 1 eV and 10 keV and smaller nuclear cross sections than thermal neutrons.
The thermal conductivity of a material is a quantitative measure of how much heat will flow through a material per unit time for a given temperature gradient. In the simplest materials the mechanism of heat transfer may be described at the microscopic level as transfer of energy through collisions between atoms and molecules. In a higher temperature region region the atoms and molecules have more kinetic energy than in a low temperature region.
