Given information
Explanation:
The full balloon will have a higher weight due to the bulk of the air within (increased downward force). On the full balloon, the weight of the air displaced by the balloon will exert an upward buoyant force. Because the balloon is both enclosed and floating in air, the weight of the air inside the balloon is the same as the buoyant force. As a result, the weight of the empty balloon and the expanded balloon will appear to be the same.
Step-by-step explanation
The empty balloon and the balloon filled air are in the same air medium, so, both the empty balloon and air-filled balloon will experience the same buoyancy force.
The buoyancy force is the weight force of the displaced fluid:
In this the case, as both empty and air-filled balloon experience the same buoyancy force, their apparent weight on the scale is the same.
