This describes the state of matter known as gas.

Here's why:

* Random motion: Gas particles move in all directions with high speeds and constantly collide with each other and the walls of their container. This random motion is what creates the characteristic pressure of a gas.

* Well spaced out: Gas particles are far apart compared to liquids and solids. This is why gases are compressible and can expand to fill their container.
