It depends how big the glass is.
Some can be 1 liter in capacity, but it is more likely to be about 450 ml or less (for a smaller glass).
A glass with less water will make a higher pitch when tapped, while a glass with more water will make a lower pitch. This is because the amount of water affects the frequency of vibrations produced by the glass when hit.
1 litre. it is 4 times larger than 0.25 litres

The refractive index of water with respect to glass is more than 1. This means that light travels faster in water than in glass, causing the light to bend when it passes from glass to water.
Generally, glass is more dense than water. (There are some types of glass which are less dense.) You can demonstrate this by gently placing a glass full of water in the sink or tub; the glass will sink, indicating that glass is more dense than water. If the glass were to float, we would know that the glass were less dense. Try this with plastic cup; the plastic is normally less dense, and will float.
1 liter of water will have more molecules than 1 liter of ice. This is because in ice, the water molecules are arranged in a more spaced out, structured manner compared to the closely packed water molecules in liquid water.
less than 1 liter
There is one liter of water in a kilogram of water. There will be more or less of other liquids depending on the density of the liquid.
If you find in beer some tasting ingredients besides the water, then beer must weigh slightly more. One of the "ingredients" is alcohol, which weighs less than water, so depending on the exact mix, it may weigh more or less.
you can use less water. don't throw trash in the ocean or liter filter our water more and don't waste water too
