Question

why do gases have no definite shape or volume​

Answer 1

Explanation:

because their constituent particles or atoms are far away from each other .

Answer 2

Answer:

As their molecules are not packed tightly.

Explanation:

Their are three states of anything-

1. solid- their molecules are tightly packed ,so they have a definite shape and volume. They are rigid. They do not take the shape of any container as they have their own shape.

2. liquid- their molecules have a little distance between them ,so they do not have definite shape but volume. They are fluids. They take the shape of the container in which they are kept.

3. gases-their molecules are freely packed so that they can move freely. Thats why they donot have a definite shape and volume . They are fluids. They also take the shape of the container .
