5. Solid matter:- It has a definite shape and volume. Activity 1:-
To prove that the solid matter has a definite shape and volume.
Observation :-
The volume and the shape of each body do not change.
Conclusion:-
Solids have definite shapes and volumes.

6. Why are the gold and copper solids?
Because they have definite shapes and volumes.

7. Liquid matter:-
It has a definite volume and an indefinite shape (it takes the shape of its container).
Activity 2:-
To prove that the liquid matter has a definite volume and an indefinite shape.
Observation:-
