What keeps the balloon to hold its shape?
The shape of the balloon is determined by the shape of the deflated rubber and the thickness of the rubber. The neck is usually thicker than the body, thus the body will expand far more than the neck. The pressure exerted upon the air by the balloon's elasticity creates the final inflated shape. If the thickness in the body of the balloon varies, the balloon will not be perfectly round. The thickness of the neck rubber forces the balloon to be more pear-shaped than spherical.
What is something you can fill a balloon with?
You can fill balloons with gasses or liquids. Lighter-than-air gasses such as helium are the best if you want the balloon to float upwards. Ordinary air is no use as it is denser than the surrounding air, making the balloon too heavy to float upwards (it will float downwards). However, hot air is less dense than cold air and therefore lighter than air.All liquids are far too heavy to float, but water balloons are generally intended to be thrown, typically at people. Water balloons are typically made of thinner rubber than air balloons thus when the balloon strikes the person, the balloon's envelope bursts, soaking the person. Water balloons also have more practical uses, such as in Foley catheters. Here, the catheter is inserted into the bladder through the urinal tract, where a balloon is inflated with sterile water to prevent the catheter from falling back out of the bladder. A valve on the end of the catheter allows the balloon to be inflated or deflated for removal.Two things are water or helium.
Is Pressure inside a bicycle tire higher than the pressure outside?
If the tyre is inflated, yes. If it has been completely deflated, no.
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.
Which gas inflates a balloon the longest carbon dioxide or helium and why?
Carbon dioxide will keep a balloon inflated longer than helium will, because its molecules are much larger and therefore less able to escape through the material of which the balloon is made.On the other hand, helium is much lighter so will give a balloon greater lift while it lasts.
How does an inflated balloon rise in the air?
It is filled with a gas that is lighter than air.
Why does a shopkeeper prefer to keep deflated footballs rather than inflated ones?
because deflated balls take less space
Why was the airplane harder to invent than the hot air balloon?
The balloon is lighter than air.

What gas is in a hot air balloon?
A hot air balloon is inflated with air and then heated by a propane fueled burner. The balloon contains air andthe products of combustion of propane, namely carbon dioxide, which is heavier than air, and steam, which is much lighter than air.

Which has more mass an inflated basketball or a deflated basketball?
an inflated because it takes up more room than a deflated one It depends on how you define the basketball. If you define it as just the rubber, then the mass does not change when it is inflated. If you consider the air inside the ball to be part of the ball then adding more air adds more mass. Mass is "stuff". Air has mass because air is stuff.
Why does shopkeeper prefer to keep deflated footballs rather than inflated ones?
An inflated football is under constant pressure (force/area) that eventually degrades it due to fatigue.
Is Pressure inside a bicycle tire higher than the pressure outside?
If the tyre is inflated, yes. If it has been completely deflated, no.
What happens to the volume of his chest cavity when he inhales?
The volume of the chest cavity is reduced on exhalation. Imagine your lungs are balloons. Imagine the volume of a balloon full of air, compared to when it is not inflated. The balloon has a greater volume when it is inflated than when it is deflated - just like the lungs do!
Why is the mass of inflated balloon is greater than the mass of the deflated 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!
Is a balloon lighter than 1 kilogram?
Is a ballon lighter than one kilogram
