Why does alcohol evaporate quickly?
Show answer & explanation
Answer: Alcohol molecules pull on each other only weakly
Alcohol weighs very little per molecule — Wrong. Molecular weight isn't the main factor. The weak intermolecular bonds allow easy evaporation.
Alcohol molecules pull on each other only weakly ✓ — Correct! Alcohol molecules have weaker attractions to each other than water molecules do. Less energy is needed for molecules to escape into the air. That's why alcohol feels cold on skin—it evaporates fast, taking heat with it!
Alcohol is very hot at room temperature — Wrong. Alcohol at room temperature isn't hot. It evaporates quickly due to molecular properties.
