Why does the boiling point of liquid rise on increasing pressure ?

Explanation

To understand why the boiling point of a liquid rises with increasing pressure, we can break it down into a series of logical steps:

### Step-by-Step Solution:

1. **Definition of Boiling Point**:
- The boiling point of a liquid is defined as the temperature at which its vapor pressure equals the external atmospheric pressure. At this point, the liquid can transition into the gas phase.

2. **Understanding Vapor Pressure**:
