A solid is one of the four fundamental states of matter. Solids have a definite shape and volume, and their particles are closely packed together in a regular pattern. The particles in a solid vibrate in place, but do not have enough energy to overcome the attractive forces between them, which is what gives solids their fixed shape and volume.
Characteristics of Solids:
Definite shape and volume: Unlike liquids and gases, solids have a fixed shape and volume, meaning they maintain their structure and size.
Particle arrangement: The particles in a solid are tightly packed together in a regular, repeating pattern.
Particle motion: While the particles in a solid do vibrate, they do not have enough energy to move past each other, which is why solids maintain their shape.
