Question

How will you prove that a gas has no definite volume ?

Answer 1

Gases have no definite volume or shape.
The air that you breathe, the helium in a balloon, and the neon
inside the tube in a neon light are gases. A gas is a substance with no
definite volume and no definite shape. Solids and liquids have
volumes that do not change easily. A gas, on the other hand, has a vol-
ume that changes to match the volume of its container

Answer 2

Gas does not have a definite volume due to the following reasons :-

1. Gases have least or the weakest forces of attraction when compared with solid or liquid.
2. Gases have the maximum number of spaces as compared to solids or liquids.
3. The particles of gas possess a great deal of kinetic energy and so the particles move away from each other during a high temperature.
