  1. 1. The Chemistry ofHot Air Balloons
  2. 2. QUICK HISTORY● The Hot Air Balloon has been around for ages, since 1783 when the firsthot air balloon was launched by Pilatre De Rozier.● Hot air balloons are large carrier balloons, they travel using the chemistrybehind rising hot air.● The hot air balloon has been remastered and put to the test of time, it hasbeen perfected to modern standards by the scientist, Ed Yost.● The hot air balloon has been a valuable asset to the world of Chemistryand is still being perfected to this day.
  3. 3. Flight of an early Hot Air BalloonThis is an image of one ofthe earliest hot air balloonstested and put into flight.
  4. 4. Chemistry of:● Hot air balloons travel can basically be summed up by the“Ideal Gas Law”, the balloon is lifted by the “increasedtemperature on the motions of molecules of a gas, and therebyon the density of the gas”.● Hot air balloons are able to stay afloat in the air for so longdue to the difference in temperature between the heated air onthe inside of the balloon and the cooler air on the outside, thedifference in temperature causes an effect of buoyancy.
  5. 5. Chemistry of:● The buoyant force acts upward on the balloon, but it isconstantly being challenged by the gravitational pull.● Hot air balloons work like this: the balloon is first assembledout in the field, putting together the smaller pieces andfinishing off any last stitchings. Then the balloon is filledwith cold air from a small fan, which is later turned to hot airusing the large burners installed into each balloon.
  6. 6. Implications:● Hot air balloons are a mystery that only God can fullyexplain. It’s a mystery how man went from once struggling totravel by land across the United States to now just simplybeing able to blow up a large balloon and fly.● God really has given us so much such we have yet todiscover.
