Temperature thermal energy

Theoretical studies indicate that for dt < 2 nm the effect of strain energy exceeds that of the room temperature thermal energy, so that it is only at small nanotube diameters that the strain energy associated with nanotube... 

In a process called direct thermolysis, at a high enough temperature thermal energy is sufficient to split water into hydrogen and oxygen. Only one reaction is involved in this process, that of equation (2.3.1). In Fig. 2.6, if the input water and output gas mixture are at the same temperature To, the minimum work input required to effect water splitting at temperature Tr can be written [60]... 

A nuclear process heat reactor was selected for this application for economic reasons. Studies (1,3) indicated that the economics of steam generation from nuclear energy are favorable where a large amount of relatively low-temperature thermal energy is required in a single-purpose plant. The source of energy used to produce the steam required is immaterial as far as the sea water evaporators are concerned.

Band theory explains the properties of insulators by proposing that these have every level in the highest occupied energy band full and so there are no available empty levels into which electrons can be promoted and hence carry energy. At 0 K, this is also true of semiconductors. Increase of conductivity with temperature implies that it is no longer true for semiconductors at higher temperatures at room temperature, thermal energy is shared between electrons and the vibration of the crystal lattice. 

Electrons fill states on the electrode from lower energies to higher ones until all electrons are accommodated. Any material has more states than are required for the electrons, so there are always empty states above the filled ones. If the material were at absolute zero in temperature, the highest filled state would correspond to the Fermi level (or the Fermi energy), Ep, and all states above the Fermi level would be empty. At any higher temperature, thermal energy elevates some of the electrons into states above Ep and creates vacancies below. The filling of the states at thermal equilibrium is described by the Fermi function, f(E),... 

A thermodynamic system in thermal equilibrium at a temperature T has its energy probabilistically distributed among all the different energy states E. At any temperature (thermal energy kT) there is a finite probability P(E) of the system being in a high energy state... 

Indications of such restricted orientation become apparent in the increasing magnitude of the Weiss constant. The Weiss constant actually depends on several factors of which three are important. These factors are (o) the possible existence of multiplet levels having energy differences comparable with normal temperature thermal energies, (5)... 

The energy to liberate donor electrons and acceptor holes is about 8 x 10 J (0.05 eV). These values are comparable to room temperature thermal energy, and most extrinsic electrons and holes should be free at room temperature. In this state, the donors and acceptors are said to be ionised, and...
