Indefinite Shape:
* Weak intermolecular forces: Liquids have weaker intermolecular forces compared to solids. These forces are strong enough to hold molecules together in a relatively close arrangement, but not strong enough to fix them in a rigid lattice.
* Fluid nature: This weak attraction allows liquid molecules to move freely past each other. They can slide and flow, taking on the shape of their container. Imagine pouring water into a glass – it assumes the shape of the glass.
Definite Volume:
* Closely packed molecules: While liquid molecules can move, they are still relatively close to each other. This means they occupy a specific volume.
* Incompressibility: Liquids are nearly incompressible. This means that their volume doesn't change significantly even under high pressure. Think of a bottle of water – you can't easily compress it into a smaller space.
In summary:
* Indefinite shape: Weak intermolecular forces allow liquid molecules to flow and take the shape of their container.
* Definite volume: The close arrangement of molecules and their incompressibility ensure that a liquid occupies a specific volume.
