SUMMARY
The maximum weight that a helium balloon can lift is determined by its volume and the density of helium compared to the surrounding air. In this discussion, a 0.12 kg helium balloon with a radius of 5.2 meters was analyzed. The calculation involves using the formula for buoyant force, which is derived from Archimedes' principle, specifically Fb = ρgV, where ρ is the density of air, g is the acceleration due to gravity, and V is the volume of the balloon. The key takeaway is that the density of helium (0.179 kg/m³) must be factored into the calculations to determine the lifting capacity accurately.
