  We consider a statistical mechanics of rotating ideal gas consisting of
classical non-relativistic spinning particles. The microscopic structure
elements of the system are massive point particles with a nonzero proper
angular momentum. The norm of proper angular momentum is determined by spin.
The direction of proper angular momentum changes continuously. Applying the
Gibbs canonical formalism for the rotating system, we construct the
one-particle distribution function, generalising the usual Maxwell-Boltzmann
distribution, and the partition function of the system. The model demonstrates
a set of chiral effects caused by interaction of spin and macroscopic rotation,
including the change of entropy, heat capacity, chemical potential and angular
momentum.
