I.Answer the following questions in short:
1.Why can't we see atoms with naked eye?
2.Can we change solid iron into liquid?If yes, how?
3. Why can't we compress the solid block of steel?
4.Why gases do not have definite volume?

Answer 1

Answer:

Radhe Radhe _/\_

1. We can't see atoms with naked eyes because the size of atoms is so small.
2. Yes, we can change solid iron into liquid by the process of melting.
3. We can't compress a solid block of steel because steel is so hard that it need tremendous amount of force to be compressed.
4. Gases do not have fixed volume because the molecules of gases move freely.
5. Liquids have to property to change shape where as solids don't. That's why liquids flow but solids don't.
