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.
ause the boigraphical heat which is being given off which can not escape from the jar because they are designed to be sealed as tight as the owner wants them to be!
put the liquid in a cup(jar, glass, etc.) on a balance then take the liquid out and measure the cupthen subtract the mass of the cup from the cup + liquid
Helium is helium. Storing it is difficult as it diffuses through many substances.
botulinum bacteria can live in the absence of oxygen. This means that they can live, grow in number, and produce the botulin toxin in a sealed jar or can
If the jar is not completely full of water, and the air inside is not completely saturated, then yes, a little bit can.

In a tightly sealed jar about 2 years is the maximum.

I sealed the pickle jar after I took out a pickle.
Water evaporates faster in the sun. It does this because the water heats up, boils, and turns from a liquid to a gas.
Yes
How long can one keep a sealed jar of 'foie gras' in the fridge?
let the water evaporate and measure the salt that is left in the jar
boil it, freeze it or leave it in a jar to evaporate
Evaporation is simply what happens when there is a lower vapor pressure in the atmosphere than is in the liquid.Think of a canning jar. Some air, at the top which is actually under vacuum so you would expect a low vapor pressure. But, the liquid in the jar will only evaporate until the vapor pressure at the top of the jar equalizes with the liquid in the jar.If there is a gradient, water (or other solvents) will move in the direction of the gradient for either evaporation or condensation.
