dissolving salt in water. the salt dissapears but if you evaporate the water,
salt will be remained.

Answer #2:
The answer is that a substance never "disappears". It may become imperceptible
to your senses, or it may move to another place outside of the region that you
are monitoring, but no substance in any realm that you can observe ever passes
into "nothingness".
The semi-exception is the situation in which mass becomes energy, but even
then, although some mass has apparently "disappeared", some energy has
apparently "appeared" ex nihilo, and if you understand the mass/energy
equivalence, then you understand that even there, nothing has appeared
or disappeared.
