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
by

1 Answer

Answer :

(1) its boiling point Explanation: 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 pres-sure 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 **** or ****.
