Two rigid balloons of equal volume are filled with neon and argon at the same pressure and temperature. Statement I: Both balloons experience the same buoyant force in air. Statement II: The balloon filled with the lighter gas can lift the larger payload.
Options:
Answer:
A
Solution:
The buoyant force equals the weight of the displaced air,
, which is the same for equal volumes. The net lift is
that force minus the weight of the gas and shell, and neon is lighter
than argon, so it leaves more for the payload. Both true. A.
