How does one define Boltzmann constant and what is its value?
The Boltzmann constant defines the proportionality of the fluid particles kinetic energy to the fluid temperature. It is commonly defined as:
k_B = R/N_A
R is the gas constant (8.31446261815324 J⋅K−1⋅mol−1)
N_A is the Avogadro's number (6.02214076×1023 mol−1)
In November 2018 the Boltzmann constant value was revised to 1.380649×10−23 J/K
