Statistical Mechanics: Can one assume an idealized gas is non-relativistic

[binbagsss]

In general when one talks about an idealized gas, should/could one assume it is non-relativistic? (s.t E=p^2/2m will hold)

many thanks

Unless explicitly told otherwise, I would always assume a non-relativistic regime.
