You have a sealed, flexible balloon filled with argon gas.The atmospheric pressure is 1.00 atm and the temperature is 2°C.Assume that air has a mole fraction of nitrogen of 0.790 (i.e., 79 mol-% N2 in air), the rest being oxygen.

(a) Explain why the balloon would float when heated. Make sure to discuss which factors change and which remain constant, and why this matters. Be complete.

(b) Above what temperature would you heat the balloon so that it would float?
