Why do weather balloons pop at certain altitudes?

Answer 1

As it rises up it goes into a region of lower pressure (pressure decreases in altitude) ans as it enters this region the gases in the balloon expand due to a thermodynamic relationship. Pressure and volume of the gas are related. PV= nRT (rearranged to P= nRT/V). So as it goes up in altitude the pressure goes down thus making the volume increase causing it to pop.

Answer 2

As pressure reduces with altitude, there's less and less force pressing on the balloon from outside so the gas inside it expands eventually making it pop. Same can happen to your lungs if you were unlucky to be exposed to vacuum and didn't breath out.

Answer 3

The internal pressure of the gasses inside a balloon remains constant while external air pressure decreases as the balloon ascends. As the balance between the two changes, the pressure inside becomes progressively greater than the pressure outside, so the balloon expands. If it expands beyond the ability of the balloon material to contain it, the balloon will burst.

Answer 4

It gets bigger because as it gets higher, the density of the atmosphere will rise when the density inside the balloon stays the same. Then because of pressure, it will get bigger and eventually pop.

Answer 5

I think it would be because at a higher altitude, there is less air pressure to the gas inside the balloon expands- Until it get's the the point where the balloon can't physically stay intact when it expands. Hope this helps! ;3

Answer 6

As the balloon rises it will expand with decreasing air pressure and become less and less dense. When it has stretched as far as it can, it will burst.

Answer 7

at altitude the balloon's external air pressure has been greatly reduced, often expanding the balloon to the bursting point.

Answer 8

Because the pressure becomes more than they can handle. Often by design, as you don't want them just floating about randomly where air liners travel
