  1. Alcohol is more volatile than water because _________ is lower than water.

    1. its boiling point
    2. its density
    3. its viscosity
    4. its surface tension
Correct Option: A

Drinking alcohol (ethanol) and a lot of other simple alcohols are more volatile than water because they are less polar. Thus, alcohol has higher vapor pressure and a lower boiling point than water; therefore, it evaporates more quickly. Its low boiling point of 78°C is what makes it possible to distill alcohol into a much stronger solution than wine or beer.
