History of Boltzmann's constant "This constant is often referred to as Boltzmann's constant, although, to my knowledge, Boltzmann himself never introduced it - a peculiar state of affairs, which can be explained by the fact that Boltzmann, as appears from his occasional utterances, never gave thought to the possibility of carrying out an exact measurement of the constant."
It is the constant of proportionality in Stefan-Boltzmann law of Blackbody radiation. Stefan Boltzmann Constant is denoted by Greek letter σ. Boltzmann's constant, also called the Boltzmann constant and symbolized k or k B, defines the relation between absolute temperature and the kinetic energy contained in each molecule of an ideal gas. This constant derives its name from the Austrian physicist Ludwig Boltzmann (1844-1906), and is equal to the ratio of the gas constant to the Avogadro constant .

As an example, the Boltzmann constant relates the average kinetic energy of particles in a gas with the temperature of the gas. Boltzmann constant k links temperature with energy Boltzmanns konstant (k eller k B) er den fysiske konstanten som knytter temperatur til energi.Konstanten har fått navn etter den østerrikske fysikeren Ludwig Boltzmann, som bidro til teorien om statistisk mekanikk hvor denne konstanten spiller en fundamental rolle. k B is the Boltzmann constant and is approximately 1.3807 × 10 −23 joules per kelvin (J·K −1), T is the absolute temperature, d p is the average pore diameter of molecules, and p is the absolute pressure. In SI units, k is 1.38 x 10 -23 J/K (that’s joules per Kelvin). How Boltzmann’s constant links the macroscopic and microscopic worlds may perhaps be easiest seen like this: k is the gas History of Boltzmann's constant "This constant is often referred to as Boltzmann's constant, although, to my knowledge, Boltzmann himself never introduced it - a peculiar state of affairs, which can be explained by the fact that Boltzmann, as appears from his occasional utterances, never gave thought to the possibility of carrying out an exact measurement of the constant." Die Boltzmann-Konstante (Formelzeichen oder ) ist eine Konstante, die in der statistischen Mechanik eine zentrale Rolle spielt.

Boltzmanns konstant (efter Ludwig Boltzmann) er en vigtig konstant inden for fysik, specielt statistisk fysik (se også termodynamik). Konstanten, der normalt betegnes k, sammenknytter begreberne energi og temperatur, og den har den numeriske værdi k = 1,380649 · 10-23 J/K. En nært beslægtet konstant er gaskonstanten R.

A semiconductor material that changes abruptly from p-type to n-type has this property. Descrizione. In effetti la costante di Boltzmann è una costante dimensionale di conversione tra la temperatura espressa nelle unità proprie e la stessa espressa nelle unità dell'energia (nel sistema internazionale, il joule): nel sistema internazionale è quindi espressa in /, le stesse unità di misura dell'entropia e della capacità termica. This video discusses Boltzmann's constant, and the alternate version of the ideal gas law using Boltzmann's constant.
Boltzmann constant. A constant occurring in practically all statistical formulas and having a numerical value of 1.3807 × 10-23 joule/K. It is represented by the letter k.If the temperature T is measured from absolute zero, the quantity kT has the dimensions of an energy and is usually called the thermal energy. At 300 K (room temperature) kT = 0.0259 electronvolt. Boltzmann constant (redirected from Boltzmanns constant) Also found in: Dictionary, Encyclopedia.
