Why does a balloon filled with carbon dioxide sink in the surrounding air?

Answer 1

The density of carbone dioxide is higher than the density of air .The formula for calculating the density is :rho=(P*M)/(R*T),where R is a constant equal to 8.314(J/mol.k) and P is pressure and T is absolute temperature so in equal temperature and pressure that the volume of two gas is equal ( air and carbon dioxide) but the atomic number of carbon dioxide is 44 and the atomic number of air is 29 so the density of carbon dioxide is higher than air and the bouyancy force cannot overcome the gravity force .It's just like when you put a piece of iron in the water.

Answer 2

Like any kind of gas it can expand balloons, if it has more pressure then outside the balloon. That's because ANY gas has MORE molecules in a certain volume when the pressure is higher. So, more molecules 'bumping' against the balloon from the inside than pushing backwards from the outside, makes the balloon expand (growing 'outside'-wards)

Answer 3

If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air.

If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.

Answer 4

A balloon filled with carbon dioxide sinks in the surrounding air because carbon dioxide is denser than the surrounding air. This difference in density causes the balloon to be heavier, making it sink.

Answer 5

Helium is less dense than air, which is mostly nitrogen and oxygen, so it will float. Carbon dioxide is denser than air, so it sinks.

Answer 6

The balloon will sink, as carbon dioxide is heavier than air.

Answer 7

Carbon dioxide is heavier than air.
