Question

which of these do not have definite volume​

Answer 1

Answer:

Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. Figure 8.2. 3: A Representation of the Solid, Liquid, and Gas States.

Answer 2

Actually Solids have a definite volume as the particles are very closely packed. Liquids can be compressed to a very negligible extent. And gases can be highly compressed.

So my conclusion is that solids and liquids have a definite volume and gases do not have a definite volume.
