Density of ice is .......... than density of liquid water.

Answer

To answer the question, "Density of ice is .......... than density of liquid water," we can follow these steps:

### Step 1: Understand the Concept of Density
Density is defined as mass per unit volume. It is a measure of how much matter is packed into a given volume.

### Step 2: Compare the Densities of Ice and Water
Ice and liquid water are both forms of H2O, but they have different densities. The density of ice is approximately 0.92 g/cm³, while the density of liquid water is about 1.00 g/cm³ at 4°C.

### Step 3: Explain the Structure of Ice
Ice has a unique tetrahedral structure where water molecules are arranged in a way that creates more space between them. This structure forms a cage-like formation, which leads to a lower density.

### Step 4: Explain the Structure of Liquid Water
In contrast, liquid water has a more compact arrangement of molecules. The water molecules in liquid form are closer together compared to those in ice, resulting in a higher density.

### Step 5: Conclusion
Since the density of ice (0.92 g/cm³) is less than that of liquid water (1.00 g/cm³), we can conclude that:

**The density of ice is less than the density of liquid water.**

### Final Answer
The density of ice is **less** than the density of liquid water.
