What is the Boltzmann Constant?

The Boltzmann Constant (k_B) is a fundamental physical constant that relates the average kinetic energy of particles in a gas to the temperature of the gas. It is expressed in units of joules per kelvin (J/K). The value of the Boltzmann Constant is approximately:
k_B = 1.380649 × 10^-23 J/K.
This constant is crucial in understanding the behavior of gases and the relationship between macroscopic and microscopic properties. (Boltzmann Constant, J/K, Gas Behavior)
