                                                  Matter in our surroundings
Question-Why do we observe that the level of water doesn't change even after  dissolving salt or sugar in it?

Answer- We observe that the level of water doesn't change even after dissolving salt or sugar in it because water and salt , both are made up of matter . Matter is made up of particles .These particles have spaces between them . So  , when we dissolve salt in water particles of salt get into the spaces between particles of water.
