A thin film of water, held by the soil particles under the influence of internal attractive force, is called which of the following water

Options

A. Ranaway
B. Hygroscopic
C. Gravitational
D. Capillarity

Answer

To solve the question, "A thin film of water, held by the soil particles under the influence of internal attractive force, is called which of the following water?" we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking about a specific type of water that is held by soil particles due to internal attractive forces.

2. **Identify the Options**: The options provided are:
- A) Rainwater
- B) Hygroscopic water
- C) Gravitational water
- D) Capillary water

3. **Analyze Each Option**:
- **Rainwater**: This is water that falls from the atmosphere and does not refer to water held by soil particles.
- **Hygroscopic Water**: This is water that forms a thin film around soil particles due to strong adhesive forces. It is not available to plants as it is tightly bound to the soil.
- **Gravitational Water**: This is water that drains through the soil due to gravity. It is not held tightly by soil particles and is also not available to plants.
- **Capillary Water**: This is water that is held in the micropores of the soil due to cohesive and adhesive forces. This water is available to plants for absorption.

4. **Determine the Correct Answer**: The question specifically refers to a thin film of water held by soil particles due to internal attractive forces. This description matches **Hygroscopic Water**. Therefore, the correct answer is **B) Hygroscopic Water**.

### Final Answer:
The thin film of water held by the soil particles under the influence of internal attractive forces is called **Hygroscopic Water**.
