- When the particles of a substance have enough energy to partially overcome intermolecular interactions, then they can move about each other while remaining in contact which describes the liquid state.
- In a liquid, the particles are in close contact, so liquids have a definite volume.
- The attractive forces between liquid particles are strong enough to hold its specific volume.
- However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
Hence, Liquids have a fixed volume.
