Step 1I'll solve this problem by explaining the molecular structure and intermolecular forces in solids and liquids.
Step 2: Molecular Arrangement in Solids
- In solids, molecules are tightly packed in a fixed, rigid crystal lattice - Molecules have strong intermolecular forces that hold them in a fixed position - This rigid arrangement gives solids:
Final Answer
Solids have definite volume and shape due to strong, fixed intermolecular forces, while liquids have definite volume but can change shape because their molecules can move more freely while remaining close together.
