Explain the rise of liquid in the capillary on the basis of pressure difference.

Explanation

To explain the rise of liquid in a capillary tube based on pressure difference, we can break down the explanation into several 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 in a capillary tube, which is a thin tube.

2. **Setup of the Experiment**:
...
