Question

Heavier gases move upwards whereas lighter gas moves downwards. State examples to support your justification.

Answer 1

Explanation:

Answer. It is just that heavier gas moves up just because it can vice-versa. The heavier gas has enough kinetic energy and velocity to move against gravity to the upper jar. Therefore, even though air is lighter, it moves downwards as it collides randomly and moves downwards.

Answer 2

Answer:

At a given temperature, heavier gas molecules have slower speeds than do lighter ones. The rms speed and the average speed do not differ greatly (typically by less than 10%). The distinction is important, however, because the rms speed is the speed of a gas particle that has average kinetic energy
