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 𝑘 or 𝑘B
- The Boltzmann constant has a value of 1.38×10−23 J/K.
- Relates the average kinetic energy of particles in a gas with the temperature.
- Fundamental in the statistical description of physical systems.
Examples
- Used in the ideal gas law: 𝑃𝑉=𝑁𝑘𝑇
- Important in the study of thermodynamics and statistical mechanics.
