Key Stage 5
Meaning
The Boltzmann constant is the molar gas constant divided by the Avogadro constant.
About the Boltzmann Constant
Denoted as 𝑘 or 𝑘/subB 𝑘=1.38×10−23 k=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: 𝑃 𝑉 = 𝑁 𝑘 𝑇 PV=NkT. Important in the study of thermodynamics and statistical mechanics.
