Question 5

Solids have a fixed volume and cannot flow. Liquids have a fixed volume and can flow easily. Gases do not have a fixed volume and expand to fill any container.

Explain, in terms of the forces between molecules and the arrangement/spacing of molecules, why solids, liquids, and gases have these properties.
