Gum swells up in the water due to

Options

A. Imbibition
B. Diffusion
C. Endosmosis
D. Turgidity

Answer

To solve the question "Gum swells up in the water due to?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks why gum swells when placed in water. This indicates a physical or chemical process that occurs when gum interacts with water.

2. **Identifying the Options**: The options provided are:
- Ambivision
- Diffusion
- Endosmosis
- Turgidity

3. **Analyzing Each Option**:
- **Ambivision**: This refers to the uptake or absorption of water by a solid substance without forming a solution. When gum is placed in water, it absorbs water and increases in volume, which aligns with the definition of ambivision.
- **Diffusion**: This is the movement of substances from an area of high concentration to an area of low concentration. While water may diffuse, this does not explain the swelling of the gum itself.
- **Endosmosis**: This occurs when a cell is placed in a hypotonic solution, causing water to move into the cell and swell. However, this term specifically applies to cells, not to gum.
- **Turgidity**: This term describes the state of being swollen due to high fluid content. While it relates to swelling, it is more commonly used in the context of plant cells.

4. **Determining the Correct Answer**: Based on the analysis, the correct answer is **Ambivision**. This is because the gum absorbs water and swells without forming a solution, which is the essence of ambivision.

5. **Conclusion**: Therefore, the final answer is that gum swells up in water due to **Ambivision**.
