Water has

Options

A. High surface tension and low thermal conductivity
B. Low surface tension and low thermal
C. High surface tension and high thermal conductivity
D. High surface tension and low thermal conductivity

Answer

To solve the question regarding the properties of water, we will analyze the options provided and determine the correct characteristics of water.

### Step-by-Step Solution:

1. **Understanding Surface Tension**:
- Water has a high surface tension due to strong hydrogen bonds between water molecules. These cohesive forces pull the molecules at the surface inward, creating a "skin" effect.

2. **Understanding Thermal Conductivity**:
- Water is known for its relatively high thermal conductivity. This means it can transfer heat effectively. The movement of water molecules increases with temperature, allowing for efficient heat transfer.

3. **Evaluating the Options**:
- Option A: High surface tension and low thermal conductivity. (Incorrect)
- Option B: Low surface tension and low thermal conductivity. (Incorrect)
- Option C: High surface tension and high thermal conductivity. (Correct)
- Option D: High surface tension and low thermal conductivity. (Incorrect)

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option C: High surface tension and high thermal conductivity**.
