What does the term volatile mean in chemical context?

In a chemical context, the term "volatile" refers to a substance that readily vaporizes at normal temperatures and pressures, indicating that it has a high vapor pressure. This property means that the chemical can easily transition from a liquid or solid state into a gas, allowing it to disperse into the surrounding atmosphere.

Volatile substances can include a wide range of chemicals such as solvents, fragrances, and certain plant oils. Their ability to vaporize efficiently is often exploited in applications such as pest control, where the release of a vapor can effectively target pests.

The other options do not accurately capture the definition of volatility. While some volatile chemicals can indeed drift far in the air due to their gaseous state, not all volatile substances will behave in that manner, and it’s not a defining characteristic of volatility itself. Similarly, describing a chemical as taking longer to disperse contradicts the very nature of volatile substances, which are characterized by their rapid vaporization and dispersal.
