The length would stay the same as the pressure inside the balloon equals the atmospheric pressure.
The air pressure inside the balloon will be slightly higher than outside. This is because the air inside the balloon is slightly compressed by the elasticity of the membrane of the balloon itself. By way of illustration, if you inflate a balloon, don't tie it and just let it go, then to everyones' amusement at parties the balloon flies crazily around the room until it is fully deflated! This fun aspect of balloons occurs as a result of the higher pressure inside the balloon escaping from the balloon to join the air in the room that is at normal pressure. Actually measuring the pressure inside the inflated balloon would require an experiment where the volume of pressurised air in the inflated balloon could be measured by a) measuring the volume of pressurised air inside the balloon by fully immersing the inflated balloon in a measuring receptacle full of water (with normal atmospheric pressure in the room pressing down on the surface of the water) and, then b) measuring the volume that the pressurised airinside the balloon would occupy once outside the balloon at normal atmospheric air pressure by inverting the measuring receptacle full of water (whilst held in a larger shallow tank of water so as to keep the measuring receptacle full of water once inverted - in the usual physics lab manner) and then release the air from the balloon into inverted water-filled measuring receptacle where it would gather in the top of the same. The difference in the two volumes would directly correlate with the difference in air pressure inside and outside the balloon.
The gas inside the inflated balloon has mass. At standard atmospheric conditions at sea level air weighs approximately one kilogram per cubic metre. A 10 passenger hot air balloon has an inflated volume of about 9000 cubic metres so the air inside the balloon weighs around nine tonnes!
Yes, there is more mass in an inflated balloon than a deflated one. The difference is the gas that was used to inflate the balloon. The gas may not weigh very much, but it does make a difference.
Assuming you are attempting to puncture a balloon and keep it intact, I would reccomend puncturing the balloon near the knot, where the rubber is thick and not streched out. If you are trying to pop the balloon, then I would puncture the balloon where the rubber is thinnest.
When in the sun the balloon gets slightly bigger, when in the refrigerator the balloon shrinks.
i probably wouldn't say the air had potential energy just that an inflated balloon has potential energy.
I'd say that an inflated balloon would be strain, but could you specify what potential energy? Chemical potential? Gravitational potential?
The air would escape through the mouth causing the balloon to DEflate
Changes in air pressure
It would get smaller as the air inside the ballon contracted.
Since there is no external pressure to counteract the internal gas pressure, the gas would expand until the balloon burst.
The hot air balloon inflated as we went down to the ground. The water raft inflated as I jumped on it.
The internal air would cool down and contract (lessen) the balloon's volume.
The length of the arrows could represent either the magnitude or the direction of the vectors. If the length represents magnitude, longer arrows would represent larger magnitudes of the vectors. If the length represents direction, the arrows would be all the same length, but pointing in different directions to represent different vectors.
If you pout a balloon in to a mountain 1st sure think that wont happen is pop .The balloon will lose pressure in the in site mach more then the off site.
I'm not very sure but I think thatthe balloon waiting to be blown up would be stronger, because inflated balloons can often pop easily.
Yes this can be done but the process would be really slow. You can try adding some yeast to hydrogen peroxide and let the balloon be tied to the bottle containing that mixture. After couple of hours you will have inflated balloon.
