when sugar is dissolved in water there is no increase in volume?

Answer 1

yes, there is no increase in volume because the space present between the atoms of water is occupied by the sugar.therefore ifsugar is dissolved in water there is no increase in volume.

Answer 2

the level of water not change when sugar is dissolved in the water. ... When salt/sugar is dissolved in water, the molecules of salt/sugar goes into the these spaces. Thus no water level rise takes place. but as we go on adding salt/sugar, a time comes when nointermolecular spaces are left.
