Water plays a key role in the biosphere. It is due to certain properties of `H_(2)O` as compared to other liquids. These are except

Options

A. higher specific heat
B. lesser thermal conductivity
C. high dielectric constant
D. high surface tension.

Explanation

To solve the question regarding the properties of water (H₂O) in the context of its role in the biosphere, we need to identify which of the listed properties is NOT characteristic of water compared to other liquids.

### Step-by-Step Solution:

1. **Understanding Specific Heat**:
- Water has a high specific heat capacity, which means it can absorb a lot of heat without a significant change in temperature. This property is crucial for regulating temperatures in the environment.
- **Hint**: Recall that specific heat is the amount of heat needed to raise the temperature of a substance.

2. **High Dielectric Constant**:
- Water has a high dielectric constant, which allows it to effectively dissolve many substances and facilitates chemical reactions in biological systems.
- **Hint**: Consider how the ability to dissolve substances is important in biological processes.

3. **High Surface Tension**:
- Water exhibits high surface tension due to the strong hydrogen bonds between water molecules. This property is essential for various biological phenomena, such as the ability of small insects to walk on water.
- **Hint**: Think about how surface tension affects the behavior of water in nature.

4. **Thermal Conductivity**:
- Water has high thermal conductivity, which means it can transfer heat efficiently. However, the question asks for the property that is NOT true for water. In this case, water does NOT have low thermal conductivity; it actually has high thermal conductivity.
- **Hint**: Remember that thermal conductivity refers to how well a substance can conduct heat.

5. **Conclusion**:
- Since the question asks for the property that is NOT characteristic of water, the correct answer is that water does NOT have low thermal conductivity. Instead, it has high thermal conductivity.

### Final Answer:
The property that is NOT characteristic of water compared to other liquids is that water has **high thermal conductivity**, not low thermal conductivity.

### Summary:
- Higher specific heat: True for water.
- High dielectric constant: True for water.
- High surface tension: True for water.
- Low thermal conductivity: **NOT true for water**; water has high thermal conductivity.
