Explain why water would completely fill a fine capillary tube which is open at both ends when one end is immersed in water.

Explanation

To explain why water completely fills a fine capillary tube that is open at both ends when one end is immersed in water, we can break down the explanation into several key steps:

### Step-by-Step Solution:

1. **Understanding Capillary Action**:
- Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces. This phenomenon occurs due to the combination of cohesive forces (attraction between like molecules) and adhesive forces (attraction between unlike molecules).

2. **Immersion of the Tube**:
