SUMMARY
To calculate the diameter of a spherical balloon required to lift 20 metric tons using helium at a pressure of 101.325 kPa and a temperature of 21.1°C, one must apply the principles of buoyant force. The buoyant force is determined by the volume of displaced air, which can be calculated using the ideal gas law and Archimedes' principle. The necessary calculations will yield the required diameter for the balloon to achieve the desired lift.
