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?

Gas is bigger than whatever it was made out of.
There isn’t more matter/it isn’t heavier … But what is there takes up way more space.
(Steam takes up far more space than the equivalent weight of water.)
