Suppose a container is evacuated to leave just one molecule of a gas in it. Let v_a and v_rms represent the average speed and the rms speed of the gas.
(a) v_a > v_rms
(b) v_a < v_rms
(c) v_a = v_rms
(d) v_rms is undefined.
digAnsr: c
Ans : Speed is constant and same for a single molecule. Thus, rms speed will be equal to its average speed.
Thus,
(c) is the correct answer.
