The molecules have enough kinetic energy to slide** over each other.

Here's why:

* Kinetic energy: This refers to the energy of motion. Molecules in a liquid have more kinetic energy than molecules in a solid, allowing them to move more freely.

* Slide: This describes the movement of liquid molecules. They are not rigidly locked in place like solids, but can move past one another.

This is why liquids can flow and take the shape of their container.
