If the jar is not completely full of water, and the air inside is not completely saturated, then yes, a little bit can.
It has nowhere to evaporate to. Evaporation is dispersion of molecules.
It depends what it is covered with. If it is covered with a cloth then, as the cloth is porous, the water will evaporate. If however you cover the bowl with something that seals the top (makes it air tight), it will not evaporate.
no
Being sealed, no water can evaporate, and it all stays inside.
let the water evaporate and measure the salt that is left in the jar
From a sealed container or pipe water cannot be evaporated.
boil it, freeze it or leave it in a jar to evaporate
Heating favors evaporation.
Is it a mixture
Water can be evaporated from a sealed container.
The jar can not handle the temperature and compression so it cracks.
In a very sealed non -porous container water is not evaporated.
