Can a balloon fly in a vacuum?
It has units of force, and the maximum possible force in nature, the Planck force, is 1044 newtons, so the balloon could get bigger than the known universe before it absolutely has to pop. Unless I’m missing something, it is a myth that balloons are inherently unable to work in space.
What happens if you put a balloon in the freezer?
The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
What happens if you fill a balloon with hydrogen and oxygen?
Hydrogen gas is very flammable and yields explosive mixtures with air and oxygen. The explosion of the mixture of hydrogen and oxygen is quite loud. Tests should be made prior to the demonstration to adjust the total volume in the balloons so that the sound of the explosion is tolerable in the room.
What happens if you fill a balloon with oxygen?
When comparing the density of helium and oxygen, you can fill a balloon with each and see which floats higher. Therefore, helium is lighter than oxygen and it will rise higher than the oxygen-filled balloon. The oxygen-filled balloon will sink, with the balloon’s material weighing it down.
Would a balloon filled with vacuum rise?
The phrase Nature abhors a vacuum sums it up nicely. If you could figure out a way to do it, however, you would be set — your vacuum balloon would float! Note that you would not need to have a perfect vacuum. Any air that you take out of the envelope will lower the weight and cause lift.
Will the balloon size grow bigger if more vinegar is in the bottle Why?
The Chemistry Explanation If you want a bigger balloon you should use more baking soda and vinegar because then more carbon dioxide gas will be produced.
What will happen if a student inflates a balloon with helium then places it in the freezer?
The colder the temperature, the smaller the volume. Thus the balloon will contract, as the gas gets colder.
How come water isn’t flammable?
The reason that water (in any state) is not flammable is that it is already the product of combustion. The chemical equation for this reaction is: 2H2 + O2 -> 2H2O. The reaction also releases a large amount of energy, mostly in the form of heat that causes the water vapor to expand rapidly to a large volume.
Why is hydrogen so flammable?
Hydrogen is very combustible because it is very reactive – it can easily combine with an oxidizer to be oxidized. In fact, hydrogen can be oxidized or reduced and can combine with every element except the noble gases.
How many oxygen molecules can fit in a balloon?
In a regular sized balloon, for example, there are about 50 trillion air molecules (including about 10 trillion oxygen molecules). A standard painkiller contains around 1.7 trillion molecules of the active ingredient. And one litre of mineral water contains about 1 trillion sodium atoms.
Can oxygen balloons fly?
Density and Weight Consequently, balloons that are more dense than air will tend to sink, while balloons that are less dense than air will tend to rise, and that’s why helium balloons fly while oxygen-filled balloons fall.
How much oxygen does it take to fill a balloon?
Let’s say 0.1 liter of oxygen at 1 atmosphere of pressure, and the balloon could hold 5 liters of air at 1 atmosphere of pressure. If the balloon is strong enough (I think it probably is) then the oxygen would expand to fill the balloon if the balloon were placed in a near total vacuum.
What happens to the size of a balloon as it rises?
Answer 3: When a balloon goes up higher in the air, its size will increase. Since there’s less air in the upper atmosphere, there’s less stuff pushing back on the balloon, and hence the pressure is lower, which allows the balloon to expand.
What would happen if you popped a balloon in space?
Air Pressure in a Vacuum. The interesting thing about this question isn’t what would happen if you popped a balloon in space, but whether you would even be the one to do the “popping”. When you blow up a balloon on Earth, the air pushed into the balloon is at a higher pressure than the air that surrounds it (1 atm).
Can a 1 liter balloon float on a vacuum?
Generally, a balloon has to be several liters in size before the 1-gram-per-liter weight difference of helium vs. air is enough to overcome the weight of the balloon itself and float. If you could somehow fill a 1-liter bottle with a vacuum, it would float even better.
