Boiling Point: FAQs
1. What is the boiling point?
The boiling point of a substance is the temperature at which its vapour pressure equals the ambient atmospheric pressure. At this temperature, the liquid phase changes entirely into the gaseous phase.
2. How is the boiling point determined?
The boiling point is affected by the ambient atmospheric pressure. Consequently, a higher pressure increases the boiling point, whereas a lower pressure decreases it.
3. Why do different substances have different boiling points?
Variations in boiling points are due to differences in intermolecular forces. Stronger intermolecular forces require a higher amount of energy to be overcome, which results in a higher boiling point.
4. How is the boiling point utilised in everyday applications?
Boiling points are critical in cooking to determine the temperature necessary for proper food preparation. In laboratories, boiling point data is used in distillation for the identification and purification of substances.
5. Which factors can affect the boiling point?
In addition to atmospheric pressure and the strength of intermolecular forces, factors such as the purity of the substance, altitude, and the presence of solutes can influence the boiling point. Quantitative changes occur whereby impurities generally increase the boiling point, and dissolved substances may lower it.
6. Why is the boiling point of water important?
Water boils at 100 °C (212 °F) under standard atmospheric pressure. This value is essential for processes such as cooking, sterilisation, and even the determination of altitude.
