Why the level of water doesn't rise when sugar is dissolved in water?
Sugar settles at the bottom.
Sugar molecules are constantly moving.
Sugar molecules get into the intermolecular spaces of water.
The water level rise is too small to notice.
When sugar is dissolved in water, it disappears because the sugar particles get into the intermolecular spaces.
When sugar is dissolved in water, it does not raise the water level in a beaker because sugar settles in the spaces of water.
If we dissolve sugar in water the sugar molecules break and get into the spaces of water molecule but when a piece of iron is placed into water it donot dissolve , why sugar breaks into molecules and iron donot.
When sugar crystals dissolve in water the level of water does not rise appreciable
