I just don’t understand what’s happening to them. Everything I’ve read says the lower external pressure causes the helium inside the balloon to expand. Does this just mean the pressure inside the balloon is rising as if I blew up a balloon to far till it bursts? Why does the balloon expand?
In: Physics
As the ballon elevates the atmospheric pressure outside the balloon drops. Once the internal air pressure is higher if he outside it will break.
