It has a definite volume and shape, a high density, it doesn't flow and it cannot be compressed by pressure.

How are the particles of a solid organised?
They are close together in a regular lattice and they only can vibrate in their positions. The IMF between them are strong

What are the characteristics of a liquid?
It has a definite volume and a moderate to high density, it takes the shape of its container, it generally flows easily and is slightly compressible

How are the particles of a liquid organised?
They are closely packed together in an irregular lattice and can move around past each other. The IMF between them is weaker than in a solid

What are the characteristics of a gas?
It doesn't have a definite volume or shape, it has a low density, it flows easily and can be easily compressed

How are the particles of a gas organised?
There are no IMF between them. They are arranged irregularly, spread very far apart, they move quickly and randomly, and collide with each other and with the sides of the container

Intermolecular space: It is large in gases and much smaller in liquids. It is reduced by pressure
