justify these statements:-

1) sand is a solid.

2) nail polish remover evaporates faster than water.

Your friend is correct.
1.Sand is actually an aggregate of small solid particles. Although it takes the shape of the container in which it is kept but the change of shape does not take place in individual sand particle. So, it is true to say that sand is made up of small solid particles.
2. The main constituent in nail polish remover is an organic compound known as acetone. There is very weak intermolecular force of attraction in between acetone particles as compared to water. So, acetone (nail polish remover) evaporates faster than water.

1. Sand or rather sand particle is solid -when we pour sand in a container we see that sandtakes the shape of the container but actually if we considera particular particle ofsand its shape doesn'tchange. Thus we see that sand particles are solid. Pouring of sand in a container leads to the arrangement of sand particles individually.

2. Nail polish remover evaporates faster than water because it is a volatile liquid.
