Final answer:

Evaporation and boiling differ in process and scope, pressure affects melting and boiling points, while impurities raise boiling points.


Explanation:

Differences between Evaporation and Boiling:

Evaporation is a surface phenomenon where a liquid turns into a gas at temperatures below its boiling point, whereas boiling is a bulk phenomenon where a liquid rapidly turns into a gas at its boiling point throughout the entire volume.

Effect of Pressure on Melting and Boiling Points:

  1. High pressure raises the melting point and boiling point of a substance, while low pressure lowers them.
  2. For example, at higher pressure, the boiling point of water increases, and at lower pressure, it decreases.
  3. Exceptions exist, such as water where high pressure lowers the melting point and raises the boiling point.

Effect of Impurities on Boiling Point:

Impurities raise the boiling point of a liquid by disrupting the crystal lattice structure that forms during boiling, requiring a higher temperature to overcome these intermolecular forces.
