Hi, I am doing a project for school where I am calculating at what height a balloon would pop from pressure while rising. At the point I am now, I have the initial pressure and the pressure it would pop at. I know work = pressure * change in volume, and that at some point I will need to use the barometric equation, but I do not know how to get there. I understand that as the balloon rises, the atmospheric pressure around it decreases while its internal pressure stays the same (or actually increases if its volume becomes smaller due to temperature change). My question is, is the pressure it would pop at the difference between the internal and external pressures? The eventual goal of my problem is to find at what height the balloon would pop, given I know the pressure it would pop at. Sorry if this is confusingly worded or poorly explained.
