I am trying to figure out the following problem. Any help would be appretiated.
Here is the question:
Estimate the average temperature of the air inside a hot-air ballon (diameter 15m). Assume that the total mass of the unfilled balloon and payload is 500kg. What is the mass of the air inside the balloon?

methods:
1. Determine the ambient temp
2. Calculate the vol of the balloon, using simple geometry
3. From the measured temp, go to Handbook of Chemistry and Physics to find the density of air at stated temp.
4. To determine the weight of the air, multiple the vol of the ballon by the density of the air.

PV=nRT P= stress V= quantity n= Moles R= customary quantity. in case you come across your stress in atm, then R will equivalent 0.0821 T= temperature till each and everything is at customary temperature and stress, you will could desire to apply that formulation. If each and everything is at STP, then you definately can use the easy conversion element of a million mol = 22.4 L
