Question

when we mix salt or sugar in water then level of water doesn't change why​

Answer 1

Answer:

Once the sugar has all dissolved, you have molecules of sugar mixed in with the molecules of water. The chemical formulas at the end are the same as they were at the start, so this is a physical change.

Answer 2

Answer:

the level of the water doesnt change because the particles of salt and sugar dissolve in water.. if u try to add salt or sugar to a super saturated solution of water, then the particles of salt or sugar that u add settle down and then the level of water rises else it wont. the particles of salt or sugar, get embedded in between the molecules of water and hence doesnt make any difference in the level of water.
