Question

Why are clouds able to float?

Answer 1

see below

Explanation:

clouds are made of water vapour , `H_2O` has molecula mass = 18 g/mol while air (that is made prinipally by oxyden and nitrogen)is more weigth: its average MM is about 29g/mol. So clouds float on air till some liquid particles are formed to gain at first an equilibrium. Than these particles become bigger and it begin to rain

Answer 2

Cloud droplets are so small, that the force of gravity does not overcome the normal updrafts of the atmosphere.

Explanation:

Clouds are formed when water vapor condenses into liquid water around a condensation nuclei (microscopic piece of dirt or something). The droplets that form are so small that it takes about 2 million of them to form a rain drop. With such a small mass to surface area ratio it only takes a very small amount of updraft to overcome the force of gravity. Even when it seems winds are very calm there is almost always some updraft which is why we almost always have some cloud in the air.

Answer 3

It is all about density. Humid air is less denser than the dry air. So this allows clouds to float.
