In Physics, Stefan-Boltzmann Constant also known as Stefan’s constant is a physical 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 . Boltzmann constant.

Traditionally, however, this constant is given a different name; it is Boltzmann’s constant, usually given the symbol \(k\). 2010-01-20 The Boltzmann constant is k = (1.380622 ± 0.000059) x 10-23 joules per °K; this value corresponds to the most accurate data (as of 1969) on the constants R and N A. The value of the Boltzmann constant can be determined directly, for example, by the experimental verification of the laws of radiation. 2005-09-21 The Boltzmann constant (k B) relates temperature to energy. It is an indispensable tool in thermodynamics, the study of heat and its relationship to other types of energy.

Boltzmanns konstant, efter Ludwig Boltzmann, är en naturkonstant som relaterar temperatur för en mängd partiklar (molekyler) till energi på partikelnivå.

where c and n are constants at a given temperature. Distance (shortest) between two dislocations = (dislocation density). -0.5.

The Boltzmann constant, once again, serves as the bridge between these two levels. The Boltzmann constant is found in semiconductor physics as well. 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:

Finding the V-I Characteristics of a diode and then determining the value of Boltzmann constant is the prime aim of this experiment.Join All Lab Experiments Se hela listan på baike.baidu.com Aunque Boltzmann vinculó por primera vez la entropía y la probabilidad en 1877, al parecer la relación nunca se expresó a través de una constante específica sino hasta que Max Planck introdujo k por vez primera, y ofreció un valor exacto (1.346×10 −23 J/K, aproximadamente 2.5% menor que la cifra que se usa hoy en día), en su derivación de la ley de la radiación del cuerpo negro en ボルツマン定数（ボルツマンていすう、英: Boltzmann constant）は、統計力学において、状態数とエントロピーを関係付ける物理定数である。統計力学の分野において重要な貢献をしたオーストリアの物理学者ルートヴィッヒ・ボルツマンにちなんで名付けられた。通常は記号 k が用いられる。特にBoltzmannの頭文字を添えて kB で表されることもある。 ボルツマンの The Boltzmann constant (k B) relates temperature to energy.It is an indispensable tool in thermodynamics, the study of heat and its relationship to other types of energy. It’s named for Austrian physicist Ludwig Boltzmann (1844–1906), one of the pioneers of statistical mechanic The Boltzmann constant, once again, serves as the bridge between these two levels.
