Boltzmann Equation

[Jasleen Kahlon]

I'm a little confused as to what exactly the Boltzmann equation is trying to explain in terms of entropy. When is it usually applied?

[Kaylee Sepulveda 4G]

Boltzmann's equation is an equation relating the entropy S of an ideal gas to the quantity W, the number of real microstates corresponding to the gas' macrostate: S = k_B ln W
where kB is the Boltzmann constant (also written as simply k) and equal to 1.38 × 10⁻²³ J/K.

[Adam Kramer 1A]

The Boltzmann equation relates microstates of a system to a macroscopic quantity called entropy. It measures the possible microstates to give a quantity of the entropy of a system.
