which way nis the balance

Question

Two identical balloons of the
same volume are pumped up with
air to more than atmospheric
pressure and suspended on the
ends of a stick that is horizontally
balanced. One of the balloons is
then punctured. Is there a change in the stick’s balance? If
so, which way does it tip?

Answer 1

Initially tipping of scale will depend on place the hole is made in the balloon. If the hole is made on top of the balloon then air coming out will try to tip the balance in its side. Just like a rocket moving up as per action and reaction principle.

 

Eventually balloon that loses air will lose mass and weight. Balance will tip towards the balloon with more air left in it.
