Give reasons : Gases have lower density compared to that of solids or liquids.

Explanation

**Step-by-Step Solution:**

1. **Understanding Density**: Density is defined as mass per unit volume (Density = Mass/Volume). It indicates how much mass is contained in a given volume.

2. **Intermolecular Forces**: In solids, molecules are tightly packed together due to strong intermolecular forces. This close arrangement results in a higher mass per unit volume, leading to higher density.

3. **Molecular Arrangement in Liquids**: In liquids, the molecules are still close together but not as tightly packed as in solids. The intermolecular forces are weaker than in solids, allowing for some movement, which increases the volume slightly compared to solids, thus reducing density.
