* Strong Intermolecular Forces: The particles in a solid are held together by strong intermolecular forces (like ionic bonds, covalent bonds, or metallic bonds). These forces keep the particles in a close, fixed arrangement.
* Limited Movement: The particles in a solid have very limited movement. They vibrate in place but can't move freely like liquids or gases. This restricted movement prevents them from flowing to conform to the shape of the container.
* Definite Shape and Volume: Because of the fixed arrangement and limited movement, solids maintain a definite shape and volume. They resist changes in their shape, unlike liquids which take the shape of their container.
Think of it like this: Imagine a bunch of tightly packed marbles in a box. The marbles can't move past each other easily, so they maintain their arrangement even if you tilt the box. This is similar to how the particles in a solid behave.
