Why is a balloon heavier when it is blown up with air?
This depends on whether you consider what is inside the balloon to be a part of the balloon, since the weight of the balloon skin will remain the same regardless of what is inside it. If, however, you consider the contents of the balloon to constitute a part of the balloon's mass then it will always be heavier when inflated, regardless of the density of the substance with which it is inflated. However, in this case the density of the balloon will fall when inflated if the contents are less dense than the material of the balloon, which is highly likely since the substance would probably be a gas. Therefore the balloon would be heavier but less dense.
Why do balloons rise in the air?
A balloon rises in the air only if the balloon has a lower mass than an equal volume of the air surrounding it.That might be the case if the balloon were filled with a light gas such as helium, for example. The balloon rises because the pressure of the air around it pushes it up in the same way that water causes an air bubble to rise.
What causes the air pressure inside an inflated balloon?
The elastic contraction of the rubber in the balloon's membrane causes the pressure in the air inside an inflated balloon. When you inflate a balloon, you have to expand the latex of the balloon, which stretches when filled with air from a pressure of 760 mm Hg to as high as 840 (about 10% higher than standard atmospheric pressure). If you inflate a non-elastic mylar balloon, it takes no effort: the air inside is at the same pressure as the air outside.
What is the difference between a full and an empty balloon?
A full balloon contains more gas than an empty balloon (even an empty balloon contains a little air). Therefore a full balloon is heavier than an empty balloon (assuming the balloons are the same weight to begin with). However, if filled with a lighter-than-air gas, such as helium, the full balloon will defy gravity due to its increased buoyancy. The only other difference is that the skin of a full balloon will be stretched and will therefore be much thinner than the skin of an empty balloon. This stretching increases the pressure upon the gas contained therein, therefore the gas is compressed inside the balloon.
Why does wet helium balloons fall?
Helium filled balloons eventually fall because the helium molecules escape from the envelope of the balloon, both at the neck of the balloon and through the material of the balloon itself. The same occurs with air-filled balloons but air-filled balloons do not float to begin with -- they fall to the ground no matter how much air you put in them. In order to float, the gas within the balloon must be lighter (less dense) than the gas outwith the balloon. Inflating a balloon with the same density of gas that surrounds it will not make it float upward because the weight of the balloon alone will make it fall under gravity. Moreover, the elasticity of the balloon compresses the gas within, making it much denser, and therefore heavier.
When a balloon is filled with air is heated does the density of the air in the balloon stay the same?
No it decreases
A balloon is filled with CO2 in the same room on the same day at the same atmospheric pressure a second balloon identical to the first is filled with O2 according to avogadro the experimenters?
the same amount of molcules in each A+
Are helium balloons more dense than air baloons?
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.
Which gas is used to fill a hot air balloon?
A typical hot air balloon is filled with the same air we breath.
What uses the same principle as a hot air balloon?
A weather balloon filled with hydrogen is also lighter than air, and will rise to great heights.
Is a flat balloon lighter than a air balloon?
depends on mass and if you include the air. same mass and not including the air they both weigh the same, air just expands the balloon and lowers the effect of gravity.
Why does a balloon filled with water neither sink or float and it just drifts and literally becomes one with the water?
The density of water molecules is the same inside the balloon as on the outside.
If you have 2 10pound buckets one filled with water and one filled with apples which weighs the most?
they would weigh the same
Does a balloon filled with heleum depend on gravity?
I am not sure what you mean by 'depend' (please try and make your questions clear) but if you mean does the fact that a helium filled balloon will float (or rise) depend on gravity? Then the answer is Yes. if you were to take a helium filled balloon to the space station and release it inside, it would not rise, it would behave just the same as if you released a bunch of keys.
Does helium contract in cold weather and cause a helium balloon to sink and if warmed will it rise again?
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain
Why do balloons filled with air not float?
Because air is not as dense as helium filed gallons so they won't float
What do air particles do to keep a balloon inflated?
It's buoyancy - the same as a ship floating in water.In this case the volume of the balloon must weigh less than an equal volume of air.(That's done by using a lighter than air gas - hydrogen, helium, or just heated air.)
