Solids are one of the three fundamental states of matter, along with liquids and gases. Here are some key characteristics of solids:
* Fixed Volume: Solids maintain a constant volume regardless of the container they are in.
* Fixed Shape: Solids retain their shape, meaning they don't flow or take the shape of their container.
* Strong Intermolecular Forces: The particles in a solid are tightly packed together and held by strong forces, giving them rigidity and structure.
