Aqueous tension of water depends on

Options

A. the amount of water taken
B. the temperature only
C. both amount of water and temperature
D. neither temperature nor amount of water

Explanation

To determine what the aqueous tension of water depends on, we can follow these steps:

### Step-by-Step Solution:

1. **Define Aqueous Tension**: Aqueous tension is the pressure exerted by the water vapor in a saturated state at a given temperature. It reflects the amount of water vapor present in the air above a liquid.

2. **Understand the Relationship with Temperature**: The aqueous tension of water is directly related to temperature. As the temperature increases, the kinetic energy of water molecules also increases, leading to more molecules escaping into the vapor phase. This results in an increase in the vapor pressure (aqueous tension).

3. **Analyze Other Factors**:
- **Pressure**: Aqueous tension does not depend on external pressure. It is a property of the water vapor at a specific temperature.
- **Volume**: The volume of the container does not affect the aqueous tension, as it is determined by the temperature and the nature of the liquid.
- **Amount of Water**: The amount of water present does not directly influence the aqueous tension, as long as there is enough water to saturate the vapor above it.

4. **Conclusion**: The only factor that affects the aqueous tension of water is the temperature. Therefore, the aqueous tension of water depends solely on temperature.

### Final Answer:
Aqueous tension of water depends on temperature.
