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.
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)
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.
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.
The balloon will sink, as carbon dioxide is heavier than air.
Carbon dioxide is heavier than air.
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
Its a compound and a pure chemical substance
No, because the density of carbon dioxide is greater than the density of air.
If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium
As the gas is pushed into the balloon the internal pressure increases, to reduce this pressure the rubbery material expands to increase the volume and ultimately reduce the pressure. Once the balloon is filled with CO2 and the knot is tied the balloon will probably sink this is because CO2 is more dense than air.
No. helium is released in outer air but does not lose or change its chemical formula
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
The balon filled with helium will cause more static,a ballon filled with carbon dioxide may be dangerous.
CO2 is heavier than a mixture of 75% nitrogen and 20% oxygen.
Its a compound and a pure chemical substance
Dry ice is frozen carbon dioxide. Sublimated carbon dioxide is heavier than room air and will not float.
Hydrogen or helium are used. As they are lighter than air that's why they float in air when filled in a balloon. Also, sometimes oxygen and carbon dioxide from your lungs, if you blew the balloon up with your mouth.
No
The abdomen is filled with gas, usually carbon dioxide, to help the surgeon view the abdominal cavity.
when you breathe underwater, those little bubbles are filled with carbon dioxide
No, because the density of carbon dioxide is greater than the density of air.
From common sense you'd think that the answer is carbon dioxide. But try it and you discover the opposite.
