Explain why light diffuses faster than a heavy gas

Lighter gases will escape faster than heavier gases because the lighter gas has the greater velocity and therefore are making more collisions, so have a greater chance of escaping. Two gases have the same Molar Mass

Explanation:

the answer for sodium is 0.186

the answer for rubidium is 0.251

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
