The Boltzmann constant (kB or k) is the proportionality factor that relates the average relative thermal energy of particles in a gas with the thermodynamic temperature of the gas. It occurs in the definitions of the kelvin and the gas constant, and in Planck's law of black-body radiation and … See more Macroscopically, the ideal gas law states that, for an ideal gas, the product of pressure p and volume V is proportional to the product of amount of substance n and absolute temperature T: See more The Boltzmann constant is named after its 19th century Austrian discoverer, Ludwig Boltzmann. Although Boltzmann first linked entropy and probability in 1877, the relation was never expressed with a specific constant until Max Planck first introduced k, and … See more • Draft Chapter 2 for SI Brochure, following redefinitions of the base units (prepared by the Consultative Committee for Units) • Big step towards redefining the kelvin: Scientists find new way to determine Boltzmann constant See more Since k is a proportionality factor between temperature and energy, its numerical value depends on the choice of units for energy and … See more • CODATA 2024 • Thermodynamic beta • List of scientists whose names are used in physical constants See more

Therefore, any relationship that we can derive between the coefficients at, say, thermodynamic equilibrium will be valid universally. At thermodynamic equilibrium, we will have a simple balancing, in which the net change in the number of any excited atoms is zero, being balanced by loss and gain due to all processes.
