Helium gas is added to a balloon, already partially filled with helium gas. Why does the balloon inflate
1 answer
The balloon inflates when helium gas is added because of the principle of buoyancy. Helium is a lighter gas than the surrounding air, so when more helium gas is added to the balloon, it increases the overall volume and displaces more air. As a result, the buoyant force acting on the balloon increases, causing it to inflate and rise.
