1.	The weight of a balloon is W_(1) when empty and W_(2) when filled with air. Both are weighed in air by the same sensitive spring balance and under identical conditions.
Answer» `W_(1)ltW_(2)` as the weight of air in the balloon is offset by the force of buoyancy on it. `W_(2)ltW_(1)` due to the force of buoyancy acting on the filled balloon. `W_(2)ltW_(1)` as the air inside is at a greater PRESSURE and hence has greater density that the air OUTSIDE. `W_(2)=W_(1)+` weight of the air inside it.
