As can be seen, radiation heat transfer is important at very high temperatures and in a vacuum . The Boltzman Constant (0.000086173324 eV/K) is a physical constant that relates a particle energy with temperature. The Boltzmann constant is the gas constant divided by Avagadro's number.

Wherever there is a p-n junction, a voltage characteristic called thermal voltage (V T ) can be related to the absolute temperature of the system with this equation: How Boltzmann’s constant links the macroscopic and microscopic worlds may perhaps be easiest seen like this: k is the gas constant R (remember the ideal gas law, pV = nRT) divided by Avogadro Boltzmann constant in eV/K: Numerical value: 8.617 333 262 x 10-5 eV K-1: Standard uncertainty (exact) Relative standard uncertainty (exact) Concise form 8.617 333 262 x 10-5 eV K-1 : Click here for correlation coefficient of this constant with other constants Boltzmann postulated that you could look at temperature as a form of energy: the thermal energy and that the thermal energy is directly proportional to absolute temperature. \[E_{thermal} = k_B T\] The proportionality constant \(k\) (or \(k_B\)) is named after him: the Boltzmann constant. It plays a central role in all statistical thermodynamics. Boltzmann’s constant by measuring the current-voltage characteristic of a 2N3904 Diode. The experimentally measured value of k = 1.35x10 -23 JK -1 is consistent with the current national institute of science and technology (NIST) value. Thus, one may prove that, because of the atomic movement in systems consisting of arbitrarily many material points, there always exists a quantity which, due to these atomic movements, cannot increase, and this quantity agrees, up to a constant factor, exactly with the value that I found in [Boltzmann 1871c] for the well-known integral \(\int Boltzmann's constant is just a conversion between energy and a made-up dimension we call "temperature". Logically, temperature should have dimensions of energy and Boltzmann's constant is just a dummy that converts between the two for historical reasons.
