Where Do Evaporants Go?

When substances such as alcohol and gasoline evaporate,
where do they go? Do they enter the water cycle?
When a substance like alcohol or gasoline evaporate the substance is
converted from a liquid (or sometimes a solid) into a gas (the more exact
term is 'a vapor'). The density of the gas (vapor) is much less than the
liquid (or solid) so it is not usually visible, but you know it is there,
mixed with air, from its odor for example. It does not "disappear" it just
is not so easily seen.
Any substance that evaporates, goes to the atmosphere
and stay there depending the temperature, partial
pressure, etc, that is the actual conditions. If
part is water, (as in alcohol that many times is
aqueous solution) the water fraction can be eventually
part of the water cycle. The other foreign
substances will constitute pollution of the air.
Heavier pollution is caused when the fuels as alcohol
and gasoline burnt at the engines leaving besides
gases microscopic particles.
Water rains wash and carries away pollution gases
and particles and they eventually pollutes even more
the soil and soil plants and again the atmosphere.
Thanks for asking NEWTON!
