The Boltzmann constant kB is a fundamental constant relating the kinetic energy of a molecule with temperature. It is equal to the ratio of the molar gas constant R to the Avogardo constant NA.
Another popular choice in the determination of the Boltzmann constant is using Johnson Noise Thermometry (JNT). The dielectric constant gas thermometry is a method that measures the responses of gas to an electric field change. JNT uses the information that the speed of sound in a gas is depend...
What is the Boltzmann constant?Boltzmann Constant:The Boltzmann constant is named after Ludwig Boltzmann, a physicist born in Vienna. The constant was named after him to honour him for his work in the field of physics. This constant is an integral part of the study of statistical physics and ...
The constant is based on Stefan-Boltzmann's law, which states that the radiant heat energy emitted from a unit area of the black body in one second (E) is directly proportional to the fourth power of its absolute temperature, or E = σ x T4. E is distributed over a range ofwavelengths...
