**Understanding Phase Changes and Boiling Point Influences****Evaporation vs. Condensation:**- **Evaporation** is the process where liquid molecules gain enough energy to transition into a gaseous state, typically occurring at the surface of the liquid.- **Condensation** is the reverse process where gas molecules lose energy and transition back into a liquid state.**Boiling Point Determination:**The determination of boiling points serves various purposes:- Identifying or characterizing substances- Assessing purity levels of a substance- Assisting in the design and operation of distillation processes**Effects on Boiling Point:**- A **soluble non-volatile impurity**, such as table salt, generally increases the boiling point of a liquid due to the elevation of boiling point effect.- An **insoluble foreign substance**, like sand, typically does not affect the boiling point significantly.**Boiling Point Under Different Pressures:**- For a liquid "X" with a normal boiling point of 75 °C, the boiling point can decrease when the pressure is reduced to 800 mmHg, as lower pressure typically lowers boiling points.

Condensation is the change of vapour into liquid and evaporation is the change of liquid into…
