### Step-by-Step Solution: 1. **Understanding Density**: - Density is defined as mass per unit volume (Density = Mass/Volume). Generally, solids have higher density than liquids because their particles are packed closely together. 2. **Identifying the Substances**: - In this case, we are comparing ice (solid) and water (liquid). Ice is the solid form of water. ...
