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:
- High pressure raises the melting point and boiling point of a substance, while low pressure lowers them.
- For example, at higher pressure, the boiling point of water increases, and at lower pressure, it decreases.
- 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.
