What is the effect of pressure on the boiling point of a liquid?

Explanation

**Step-by-Step Solution:**

1. **Understanding Boiling Point**: The boiling point of a liquid is the temperature at which its vapor pressure equals the external pressure surrounding the liquid. At this point, the liquid turns into vapor.

2. **Effect of Pressure on Intermolecular Forces**: When pressure is increased, the intermolecular spaces between the molecules of the liquid decrease. This means that the molecules are pushed closer together.

3. **Energy Requirement**: With decreased intermolecular spaces, more energy (in the form of heat) is required for the molecules to overcome the attractive forces holding them together. This means that the boiling point of the liquid will increase.
