Question

VII. Give short answer
ible
as:
1.
A rubber ball changes its shape on
pressing. Can it be called a solid?
2. Why do gases not have fixed shape​

Answer 1

Answer:

A.Though rubber ball changes shape by pressing with hand, still it can be said to be solid as it follows the properties of solid which state that the atoms should be closely bonded in the material firmly with each other though they can move some bit to change the shape.

B.Gases don't have a fixed shape or a fixed volume. The particles move around all the time and spread out. This is why a gas fills its container. A gas can be compressed into a very small space – this pushes the particles closer together.

Answer 2

Explanation:

1. yes rubber Ball is solid when it is compressed there are no intermolecular space left....

2. While gases do not have intermolecular force of attraction and also they do not have any boundry and intermolecular space is too much in gases
