Yes, the mass of the sealed cup of water would remain the same as long as no water is added or removed from the cup. The mass is a measure of the amount of matter in the system, which would not change in a sealed environment.
If it is not a sealed battery you add distilled water when the level is below the top of the fill hole which is usually about 1/2" below the top.
If it is not a sealed battery you add distilled water when the level is below the top of the fill hole which is usually about 1/2" below the top.
no, it will not add substances but may or will evaporate just giving the water in a different form but keeping its same properties .
Most likely no. Automotive batteries are generally maintenance free and the water level is sealed.
