Answer 1

Answer:

When a 50gm of sugar is added to a beaker containing 100 ml of water and is stirred for a while.

The following observations can be made:

1. We observe that sugar gets dissolved 

2. Level of water after dissolving sugar is same as before adding sugar. That means there is no increase in its volume.

3. We can conclude that there as spaces between the particles of water and these spaces accommodate sugar particles. 

4. Particles in water are not tightly packed. They have spaces in between them.
