* They take the shape of their container. Unlike solids, which have a fixed shape, liquids will flow and conform to the shape of whatever container they are in.

* They are not rigid. The molecules in a liquid are not locked into a rigid structure like those in a solid. They can move around freely, allowing the liquid to change shape.

* Surface tension creates a "surface" but not a fixed shape. Liquids have surface tension, which causes them to form a surface. This surface can appear to give the liquid a shape, but it is still influenced by the container.

Think of these examples:

* Water in a glass: The water takes the shape of the glass.

* Water in a bottle: The water takes the shape of the bottle.

* A puddle on the ground: The puddle takes the shape of the ground.
