In thermodynamics, Boltzmann constant is the physical constant relating average kinetic energy of the gas particles and temperature of the gas represented by k or kB. The value of Boltzmann constant is measured using J/K or m2Kgs-2K-1. Which is mostly observed in Boltzmann’s entropy formula and Planck’s law of Black body radiation.
Value Of k
The values of Boltzmann constant is got by dividing gas constant R by Avogadro’s number NA. The value of k or kB is
Boltzmann constant k or kB = 1.3806452 × 10-23 J/K.
Value Of Boltzmann Constant In eV
The value of Boltzmann constant in eV is 8.6173303 × 10-5 eV/K
The value of Boltzmann constant can be expressed in various units. The table given below comprised of the value of k along with different units.
| Value Of k | Units |
| 1.3806452 × 10-23 | m2.Kg.s-2.K-1 |
| 8.6173303 × 10-5 | eV.K-1 |
| 1.38064852 × 10-16 | erg.K-1 |
Boltzmann Constant
The Boltzmann constant is introduced by Max Plank and named after Ludwig Boltzmann. It is a physical constant obtained by taking the ratio of two constants namely gas constant and Avogadro number.
Boltzmann constant Formula
The behavior of gases made to understand a step closer by Planck and Boltzmann by introducing constants. Boltzmann constant is mathematically expressed as-
\(k=\frac{R}{N_{A}}\)Where,
- K is Boltzmann’s constant.
- NA is Avogadro number.
- R is the gas constant.
Hope you got to know the value of Boltzmann constant or value of k or value of kb in different units along with the Boltzmann Constant formula, definition in Physics.
