My chemistry professor asked this in class, using vodka as the beverage of choice, probably because of its basic ingredients, but why does the 40% ethanol value not change overnight, especially with evaporation?

same volumes of water and alcohol evaporate every hour.
Pure alcohol evaporates faster than pure water, and 40% mix exactly offsets that .
Btw, this was discovered by Mendeleev, same guy who did periodic table.

If you mix equal vol of ethanol and h2O, you have less than twice their combined vol. The two do have attractive forces that would affect their vapor points or not?

Ethanol and water have similar boiling points

More alcohol experiments please!!!
What about flys that land in it.
Do they drown or do they die of alcohol poisoning?
