Boltzmann Constant

A Boltzmann Constant is a fundamental physical constant relating particle energy level with temperature.

• Context
  • It is generally represented as [math]\displaystyle{ k_B }[/math] and its value in SI units is 1.38064852(79)\times10^{−23} J/K. (Joules per Kelvin)
  • It is the gas constant divided by the Avogrado constant, i.e. [math]\displaystyle{ k_B=R/A_0 }[/math]
• Counter-Example(s):
  • Avogrado Constant.
• See: Ludwig Boltzmann, Fundamental Gas Constant, Partition Function, Entropy, Ideal Gas Law, Gas Pressure.

  • The Boltzmann constant (k_B or k), named after Ludwig Boltzmann, is a physical constant relating energy at the individual particle level with temperature. It is the gas constant R divided by the Avogadro constant N_A:

[math]\displaystyle{ k = \frac{R}{N_\text{A}}.\, }[/math] The Boltzmann constant has the dimension energy divided by temperature, the same as entropy. The accepted value in SI units is 1.38064852(79)\times10^{−23} J/K.
