💡 What Does "Volatile" Mean?

In chemistry, a volatile substance is one that:

Easily changes from liquid (or solid) to vapour at room temperature.

🔬 Scientific Meaning:

  • A volatile substance has weak intermolecular forces, so its molecules escape easily into the air.

  • As a result, it has a high vapour pressure.

  • The more volatile a substance is, the faster it evaporates.

🧪 Examples of Volatile Substances:

  • Perfume (evaporates quickly)

  • Alcohol

  • Petrol

  • Nail polish remover (acetone)

📌 In Simple Words:

"Volatile" means the substance evaporates easily and can quickly become gas or vapour.

📘 Board Tip:

Use this definition:
"A volatile substance is one that has a high vapour pressure at room temperature and evaporates easily."
