In order for a gas-filled balloon to rise in air, the density of the gas in the balloon must be less than that of air. Consider air at 25 ∘C and 1 atm to have a molar mass of 28.96 g/mol. Determine the minimum temperature to which the balloon filled with argon at 1 atm would have to be heated before it could begin to rise in air. (Ignore the mass of the balloon itself.)
