Temporal relaxation properties of the velocity distribution of small amount gas A of mass mA injected into ambient gas B of mass mB in thermal equilibrium at temperature TB are investigated with the Boltzmann equation rewritten in a linear form. Even if started from an equilibrium state at TA, the velocity distribution of A gas can not be in the Maxwellian form in transient stage but finally settles in the Maxwell distribution at TB. Temporal variations of the fractional changes of the mean energy and the H function show the relaxation behavior quite frankly. The relaxation properties are discussed in various aspects.
