I’m thinking of like when you bottle wine that’s still fermenting, and it explodes. I understand that the fermentation process raises the air pressure inside the bottle. What I *don’t* understand is how? When you pump air into a balloon, the air pressure rises because there are *more* air molecules entering the balloon.
With wine in a bottle, you have a fixed amount of matter at a certain temperature. I don’t understand how fermentation could increase air pressure in a closed system?

If I ball up a fist and you wrap a piece of paper around my fist, I can open my fist to expand my hand and tear the paper, even though there was no increase of matter in my hand.
Not all matter takes up the same amount of space 100% of the time.
