How does alcohol (booze) change from an alcoholic beverage to non alcoholic when left sitting out exposed to air?

I once left a cup of vodka in my room for over a day and I remember sipping it and it no longer tasted like vodka. It was bitter but didn’t have that “burn” to it. How long and also what is the chemical process that changes it into a non-alcoholic or less alcoholic beverage.

Side note: this popped into my head because I had a random hypothetical situation pop into my head. It goes like this: I’m in a position where someone has power over me. They encourage me to drink and I’m a lightweight but I know getting drunk isn’t wise. I also don’t have a choice. Would there be ANY possible way for me to fill my mouth with alcohol, hold it in there and then like open my mouth and let that alcohol aerate and settle and become less alcoholic, therefore not affecting me as much? I know this is a very unrealistic scenario I’m just very curious!

Ethanol has a lower evaporation temperature than water. If you leave a pond of water there at room temperature, after a day or two it will be gone. Same with alcohol, just faster, and you will still have the water there because it takes a little more time to evaporate.
