Hot air balloons rise when atmospheric gases are heated, typically by burning propane, and the density of the gases decreases. While you are watching one of these balloons rise, a large rip appears. Which of the following atmospheric gases present will be the first to escape? Argon (Ar), Carbon dioxide (CO2), Nitrogen (N2), or Oxygen (O2) ? State you answer, then briefly explain why you chose your answer.

5. A very large hot air balloon and its accompanying structure (i.e. the basket, rigging, equipment, etc) have a mass of 400 kg. The air inside the balloon must be heated to a temperature of 200 OC for the balloon to lift off the ground when the outside air temperature is 16.0OC. To what temperature must the air be heated if the balloon is to lift off with three 80.0-kg people aboard? Note: Problem 5 requires three pictures of the...
