Homework Answers
In chemistry, volatility is a term used to characterize the tendency of a substance to vaporize at a given temperature, a substance with a higher vapor pressure will vaporize more readily than a substance with a lower vapor pressure.
Pentane is the most volatile with Boiling point 35-36 oC
