The liquid soaking the dollar bill is a mix of alcohol and water. As the alcohol burns, the water evaporates. Why doesn't the heat from the burning alcohol cause the bill itself to char or burn?

Select the best answer from the choices provided.

The heat from the burning alcohol causes the water to evaporate. This takes away energy, keeping the temperature too low for the bill to ignite.
The mix of alcohol and water has a lower boiling point than pure water, which keeps the bill cool.
Water vapor condenses on the bill, keeping it wet, which keeps it from burning.
