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?
In: Physics
the ideal gas law is PV = nRT, where P = pressure and n = number of moles of gas. In fermentation, if solid reactants are being converted into gaseous products, the number of moles of gas in the system increases, thereby increasing pressure.
