WebUsing the Boltzmann constant, the formula to derive the constant is expressed as the following: σ = (2 x π 5 x k B4) / (15 x h 3 x c 2) = 5.670367 x 10 -8 W / (m 2 x K 4) Here: k B = Boltzmann constant = 1.380649 x 10 -23 joules per K (J x K -1 ); h = Planck's constant = 6.62607015 x 10 -34 joule-seconds (J x s); and 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 temperature.
