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'd say that an inflated balloon would be strain, but could you specify what potential energy? Chemical potential? Gravitational potential?
It would be easier to catch an inflated balloon because it is lighter and slower moving compared to a heavy cinder block. The balloon also has air inside it, which cushions its impact when caught.
The air would escape through the mouth causing the balloon to DEflate
Yes, the air in an inflated balloon has potential energy due to the elastic potential energy stored in the balloon's stretchy material. When the balloon is released, this potential energy is converted into kinetic energy as the air rushes out.
Changes in air pressure
It would get smaller as the air inside the ballon contracted.
A 31-inch balloon would have a diameter of 31 inches when fully inflated. This means the width of the balloon, from one side to the other, would be approximately 31 inches.
The hot air balloon inflated as we went down to the ground. The water raft inflated as I jumped on it.
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.
The charge on the balloon would be -1.6 x 10^-12 coulombs.
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.
The balloon would expand due to the lack of atmosphere on the moon, but it wouldn't burst because the pressure inside the balloon would equalize with the low pressure outside. Additionally, the balloon would float in the lower gravity environment of the moon.
