How to tell which packages are held back due to phased updates. So, this is an application of Avogadro's law (which is derived from the ideal gas law or PV = nRT where P is the gas pressure, V is the volume occupied by the gas, n is the moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin). Therefore, if you were to fill a 1-liter soda bottle full of helium, the bottle would weigh about 1 gram less than the same bottle filled with air. The temperature of the helium in the balloon was increased. Note that this assumes the air behaves ideally (obeys $PV = nRT$), and, as we said before, the balloon exerts no additional pressure on the helium gas (if we had a metal balloon, the buoyancy would decrease with altitude of course since the volume of helium would be fixed but the air density would be decreasing). We can find the value for n by dividing the mass of helium gas by its molar mass: n = number of moles = mass of sample molar mass. At an altitude of $30$km, the temperature is $-46.6$C $\approx 226.9$K, the pressure is $1.20$kPa, and the density is $0.0184\text{kg}\text{m}^{-3}$. There is something incredibly neat about helium balloons! Why do helium balloons expand in volume as they go higher? Approximately the same number of atoms of each of these elements fills approximately the same amount of space. The volume is then: Volume (cm^3) = Weight(gm)/1(gm/cm^3), (neglecting the weight of the empty balloon.)
