What is votility?

• A. A measure of density
• B. A measure of the tendency of a substance to vaporize
• C. A measure of melting point
• D. A measure of color

Answer: (B)

Volatility is the tendency of a substance to vaporize. In practical terms, a highly volatile liquid tends to turn into vapor more readily at a given temperature, which means it has higher vapor pressure and a lower boiling point. This property is important for fuels and solvents because it influences evaporation rate, starting characteristics, and vapor-related safety concerns. The other options describe different properties: density (mass per volume), melting point (temperature at which a solid becomes a liquid), and color (visual appearance). So volatility specifically measures how readily a substance vaporizes, making it the correct choice.
