sackurTetrode is a constant used in the Sackur–Tetrode equation for the entropy of a classical monatomic ideal gas.
The equation combines volume, particle number, mass, and thermal energy with boltzmann and planckConstant.
It assumes an ideal, dilute, classical monatomic gas; quantum degeneracy and interactions require other models. Use log only with dimensionless arguments after forming the correct expression.
