Question : Alcohol is more volatile than water because ________ is lower than water.
Option 1: its boiling point
Option 2: its density
Option 3: its viscosity
Option 4: its surface tension
Correct Answer: its boiling point
Solution : The correct answer is its boiling point.
Because of its low boiling point of 78°C, distilling alcohol yields a much stronger solution than wine or beer. Because they are less polar than water, drinking alcohol (ethanol), and many other simple alcohols are more volatile. Alcohol vaporizes more quickly because it has a higher vapour pressure and a lower boiling point than water.
