Question:

As the pressure on the refrigeration liquid increases, the boiling point of the refrigeration liquid _____.

A Increases
Explaination

The boiling point of the refrigeration liquid depends on the surrounding pressure. Liquids vaporize when the molecules are apart and faster. As pressure increases, an external force is applied on the refrigerant molecules so that they are close to each other. Therefore, boiling point of the liquid increase with the increase in pressure.
