Boltzmann's constant k is a bridge between macroscopic and microscopic physics. Macroscopically, one can define a (gas scale) absolute temperature as changing in proportion to the product of the pressure P and the volume V that a sample of an ideal gas would occupy at the temperature:

An equation used to study the nonequilibrium behavior of a collection of particles; it states that the rate of change of a function which specifies the probability of finding a particle in a unit volume of phase space is equal to the sum of terms arising from external forces, diffusion of particles, and collisions of the particles. Also known as Maxwell-Boltzmann equation.

What's "K" ?
