I would say an air filled balloon if you fill it with just plain air. I am basing this on the principle of osmosis and diffusion. A substance such as a gas will travel from an area of increased concentration, such as a balloon filled with helium, to an area od decreased concentration, such as the room the balloon is in. If you fill the balloon with air identicle to that in the surrounding room it negates diffusion.

A helium-filled balloon will float, and even soar, in the air longer but will lose its helium faster. A breath-filled balloon will stay inflated longer, but it won't float in the air at all.*

* A breath-filled balloon is too dense to float in air.

Leaving concerns about the purity of the gas aside, Helium has only 92% of the lifting power of Hydrogen or ,stated a different way, in equal amounts, Hydrogen can lift more than Helium.

Oxygen filled balloons will not fly away and the oxygen molecules are larger so they will not leak through the rubber of the balloon as quickly.

Why does a CO2 filled balloon deflate quicker than a helium filled balloon given that helium atoms are smaller and monatomic?

Well...it's because they're not the same balloons. There is a product out there called Super Hi-Float. You coat the inside of a balloon destined to be filled with helium with it, and it helps seal the pores of the latex hence holding the helium in longer. You probably wouldn't do this with a balloon you're going to fill with CO2.


Why does a helium filled balloon float up when it is released?

The gas helium is less dense than the nitrogen-oxygen mix of atmospheric air. So a balloon filled to the same pressure (or even higher) will have a lower density than the air around it, which will displace it (flow under it), forcing it upward. The balloon will rise until the combined weight of the helium and the balloon are the same average weight (density) as the surrounding air. Long before it reaches that altitude, a normal balloon will begin to expand and will usually pop (at an altitude of a few hundred to a few thousand feet).Helium molecules are lighter than most air molecules in the atmosphere (mostly nitrogen and oxygen) therefore they are prone to rise while heavier molecules move downward.


When you put a balloon in a cold room then in a worm room does its density change?

No. The volume of the helium will change as it expands the balloon due to the increase in temperature. The density of an element never changes. The reason for that is because density is just a fancy way of saying 'The atoms are this far apart' in the equation mass/volume = density.


Is a balloon more dense or less dense than the surrounding air?

Because that's what density does. Whenever an object is immersed in a medium with higher density than the object, the object will try to rise to apoint where its buoyancy(lifting force) equals the pull of gravity.


Will a basketball blow up if you put helium in it?

That all depends how much helium you put in it. A basketball should be able to take the same amount of pressure, whether it's pressure from air or helium. So, if you inflate it only to the recommended pressure, it should be a problem. The same amount of pressure of helium will be less mass, so in the end the basketball will be lighter, as you would probably expect, by a very small amount.

What happens to the pressure of the air outside of the balloon as it goes higher?

The pressure inside the balloon will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.

What happens to the atmospheric pressure acting on the balloon as the balloon rises?

due to pressure inside the balloon, will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.


Which balloon would fly higher the one with helium or the one with air?

The balloon with helium.


What usually happen to a toy hellium filled balloon that rises high into the atmosphere?

It will usually burst. As it gets higher, outside air pressure is less, helium in balloon expands until balloon pops.

Why does a helium balloon pop as it goes higher in the sky?

a helium balloon pops as it goes higher because the different combination of pressure. you could take a balloon in an airplane because the cabin is pressurized. as it gets higher the amount of pressure changes so it pops the balloon.

What happens to balloons when they are let go?

well it depends what type of balloon it is if it is filled with helium it will float higher and higher until it will pop under the air pressure. but if it a ballon filled with normal air it will just float back down or get blown away if there is wind


How do air balloons lift off from the ground?

Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.
