3. Matter:- anything
which occupies
some space and
have some mass is
called matter.

6. 1.Solid
2.Liquid
3.Gas

7. 1. Solids feels hard.
2. Solids are rigid and can’t
be compressed.
3. Solids have definite
volume.
4. Solids have definite
shape.
5. Intermolecular space is
least.

8. Atoms are tightly packed in solids and
intermolecular space is least.
So they can’t move.

10. 1. They are slippery and feels wet.
2. They are not rigid can be
compressed to a little extent.
3. Liquid have definite volume.
4. Liquids take the shape of the
container in which they are
placed.
5. Intermolecular space between
the atoms is more then solids.

11. 1. Intermolecular space between
atoms is grater then solids.
So they can flow.

13. 1. Gases are invisible.
2. They are not rigid and can
be easily compressed.
3. Gases have neither definite
volume nor fixed shape.
4. Gases can flow in all
directions.
5. Intermolecular spaces
between atoms is
maximum.

14. 1. Intermolecular space between
atoms is maximum.

16. Q: Why solid can not flow but
liquid and gases can?

17. Ans: As in solids intermolecular
space is least and atoms are
tightly packed so, they can’t
move. But in liquids
intermolecular spaces between
the atoms is more then the solids.
So, they can move randomly and
can flow. Now in gases
intermolecular space between
atoms is maximum So, they can
vibrate around their position
easily and that is why gases can
freely move.

18. ________ is the substance
which can exist on the three
states of matter.

19. Ans: Water is a
substance which can exist in
all the three states of matter.
1. Water --- Liquid ----
2. Ice --- Solid ----
3. Vapour ---- Gas -----
