Is the boiling point directly related to the volatility of a substance?

Click For Summary
SUMMARY

The boiling point of a substance is inversely related to its volatility, which is quantitatively assessed through vapor pressure. While a general trend exists where more volatile substances exhibit lower boiling points, exceptions can occur. For instance, certain substances with strong intermolecular forces may have higher boiling points despite being volatile. This indicates that volatility is not solely determined by boiling point but also by molecular interactions.

PREREQUISITES
  • Understanding of vapor pressure concepts
  • Knowledge of intermolecular forces
  • Familiarity with phase transitions
  • Basic principles of thermodynamics
NEXT STEPS
  • Research the relationship between vapor pressure and boiling point in various substances

  • Explore examples of substances that defy typical volatility and boiling point trends
  • Learn about phase diagrams and their relevance to boiling and volatility
USEFUL FOR

Chemistry students, chemical engineers, and professionals in materials science seeking to understand the relationship between boiling points and volatility in various substances.

I know that volatility is more or less proportionally related to vapor pressure.

If they are directly related, are they any exceptions where a more volatile substance may have a higher boiling point than a less volatile substance?

I wonder if volatility is defined precisely enough - as long as it is just a tendency of substance to vaporize (without any numerical/exact approach) sounds like more volatile substances will always have lower boiling points.
