Question

Collect different solid objects from your surroundings like chalk, spoon, pen, pencil, eraser and sharpener
keep them in different containers and observe the shape of these objects in those containers. Verify all other
properties of matter. Answer the following questions on the basis of your observations.
1 Do they have a definite shape?
2. Are all the collected objects rigid?
3. Are you able to compress these objects? Prepare a report.

Answer 1

Answer:

Explanation:

Articles required-

a pen,

a book,

a needle

a piece of wooden stick.

Process-

• Collect the following articles— a pen, a book, a needle and a piece of wooden stick.

• Sketch the shape of the above articles in your notebook by moving a pencil around them.

• Do all these have a definite shape, distinct boundaries and a fixed volume?

• What happens if they are hammered, pulled or dropped?

• Are these capable of diffusing into each other?

• Try compressing them by applying force. Are you able to compress them?

observation-

nothing happens to a needle and a book if we hammer them but the others are broken into pieces.

Conclusion-

all these have a definite shape, distinct boundaries and fixed volumes, that is, have negligible compressibility. Solids have a tendency to maintain their shape when subjected to outside force. Solids may break under force but it is difficult to change their shape, so they are rigid..

Answer 2
