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.
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.
How high does a hot air balloon rises?
It rises until the air it displaces weighs no more than the balloon and everything hanging from it weighs.
Which balloon has more rubber?
The simple answer is the bigger the balloon, the more rubber it will have. However, the actual amount of rubber is determined by its thickness. Thus a large but thin balloon can easily have less rubber than a smaller thicker balloon. Assuming all rubber balloons are made from the same chemical composition, you can determine which has the most rubber simply by weighing them while they are completely deflated. Alternatively, immerse the deflated balloons in water to determine their mass (by the amount of displacement).
If something is bigger than something does it mean it weighs more?
Not necessarily. For example a balloon is bigger than a baseball, but which weighs more?
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!

Which would be heavier and why a flat tire or an inflated tire?
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.
How can an inflated balloon help you define matter?
an inflated balloon has air in it so it takes up more space and matter is something that takes up more space so here by defining matter.
What will happen to an under-inflated balloon if left in sun?
It will inflate a bit more.
Does an inflated bike tube weigh more than a deflated bike tube?
It certainly would be heavier. Air has mass and will add weight.

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.
What would be the length of the arrows if the balloon were inflated more?
The length would stay the same as the pressure inside the balloon equals the atmospheric pressure.

It rises until the air it displaces weighs no more than the balloon and everything hanging from it weighs.
What volume of helium in a balloon half a mm thick?
You will need to know the actual size of the balloon as the bigger its inflated the more gas volume required.
