Why solids have definite shape and volume ?

Explanation

To understand why solids have a definite shape and volume, we can break down the explanation into a few key points:

### Step-by-Step Solution:

1. **Intermolecular Forces**:
- In solids, the particles (atoms, molecules, or ions) are held together by strong intermolecular forces. These forces can be ionic bonds, covalent bonds, metallic bonds, or van der Waals forces, depending on the type of solid.
- Because these forces are strong, they keep the particles closely packed together.
