Gas close to zero Kelvin

    Consider an adiabatic expansion of an ideal gas that work is done against friction or a piston. Since no heat exchange can occur the gas keep on losing energy and its temperature decreases and the gas molecules getting further and further apart. In principle the temperature can get down to a few degrees Kelvin, close to zero K.

    Is it possible that a gas can still be a gas at such a low temperature?
