Hot air balloon.

Postby Wattie » Mon Nov 25, 2013 10:55 pm

Hi all,
I was wondering about the weight of H2O V CO2. When fuel burns it produces both gasses with approx the same quantities. In relation to a hot air balloon, as the fuel is burnt would both gasses pass into the balloon and since CO2 is heavier than water.

Would the CO2 drop out the bottom leaving the lighter water to increase the lift. Just something that I was thinking about the other day.

No, when gases are intermingled, it takes a lot to separate them. A change of state of one of them can help. Hence you have liquid air plants to separate oxygen and nitrogen and argon.

Carbon dioxide and water are easily separated if you condense the water, but gravity isn't going to do anything significant.

Though carbon dioxide is considerably denser than than air, it doesn't sink to the surface of the Earth and extinguish life, even though it has unlimited time to do so.
