Question

Ballons are still used to deploy sensors that monitor meteorological phenomena. It is possible to investigate some of the technicalities of ballooning by using perfect gas law. Suppose your balloon has a radius of 3.0 m and that is spherical.

What mass of H₂ (in mol) is needed to inflate it to 1.0 atm in an ambient temperature of 25^oC at sea level?
What mass can the balloon lift at sea level,where the density of air is 1.22 kg /m³?
What would be the payload if He were used instead of H₂?

Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
