Meaning
The Boltzmann constant is the molar gas constant divided by the Avogadro constant.
About the Boltzmann Constant
- The Boltzmann constant denoted by the symbol π or πB
- The Boltzmann constant has a value of 1.38Γ10β23 J/K.
- The Boltzmann constant relates the average kinetic energy of particles in a gas with the temperature.
- The Boltzmann constant is fundamental in the statistical description of physical systems.
Examples
- Used in the ideal gas law\[ππ=πππ\]
- Used in the formula relating the kinetic energy of molecules to their temperature in an ideal gas\[/frac{1}{2}mv^2=/frac{3}{2}k_BT\]
- Important in the study of thermodynamics and statistical mechanics.
