Answer

Melting Point
The melting point of a substance is the temperature at which it transitions from a solid to a liquid state. This phenomenon occurs when the thermal energy is sufficient to overcome the intermolecular forces holding the solid structure together.
- Characteristics:
- The melting point is a specific temperature for pure substances.
- For mixtures, it can be a range of temperatures.
- It is influenced by atmospheric pressure; higher pressure can raise the melting point.
- Significance:
- Used to identify and characterize materials.
- Important in determining the purity of a substance; impurities typically lower the melting point.

Boiling Point
The boiling point of a substance is the temperature at which its vapor pressure equals the external pressure surrounding the liquid, leading to the rapid formation of vapor bubbles within the liquid.
- Characteristics:
- Like the melting point, the boiling point is a specific temperature for pure substances.
- It varies with changes in atmospheric pressure; lower pressure lowers the boiling point.
- Significance:
- Crucial in processes like distillation and cooking.
- Indicates the volatility of a substance; compounds with lower boiling points evaporate quickly.
