Here's why:
* Solids: In solids, molecules are held together by strong intermolecular forces, causing them to vibrate in fixed positions. This creates a rigid structure with very little space between molecules.
* Liquids: In liquids, molecules have more freedom to move around than in solids. They are still close together, but they can slide past each other. This means that there is more space between them than in solids.
* Gases: In gases, molecules are very far apart and move freely. They collide with each other and the walls of their container, but they don't have strong attractive forces holding them together. This results in much more space between gas molecules than in liquids or solids.
