Using your knowledge of boiling points and intermolecular forces, why do you think rubbing alcohol dries so quickly from your skin?

Due to its weak intermolecular forces which make it volatile.

Explanation:

Hello,

In this case, antiseptic alcohol which chemically named as ethanol has a low boiling point (78.37 °C) and weak intermolecular forces of dipole-dipole kind, which make it volatile, it means it tends to rapidly vaporize even when it is not gently heated, therefore, even a weak force such as rubbing it, is enough to vaporize it out from the skin so it quickly dries.

Best regards.

i wish i could but this one is weird give me abc and i can solve it.
