Balloon expansion and maximum height
When the ballon is made of elastic material, it
expands
because of the excess pressure inside. Its volume increases and its internal pressure decreases. As it expands, its buoyancy increases, but not the pull of gravity, so it continues to rise as a result of the expansion.
What happens to the ordinary balloon after you let go of the string?
As altitude increases,
the density of the atmosphere decreases
. So as a latex helium balloon rises, the outside air pressure diminishes, while the pressure from inside of the balloon remains the same. This causes the elastic material of the latex helium balloon to expand.
What happened with the balloons?

What will happen when two balloon?
2.1.
Thus, providing both the balloons are inflated to the size bigger than the threshold, the air pressure of the smaller one is larger than that of the bigger one. Therefore, once two balloons are connected,
the smaller balloon pushes out some of its air, while shrinking, to the bigger one
, which becomes even bigger.
Why are balloons banned?
According to the US Fish & Wildlife Service, birds, turtles and other animals commonly mistake balloons for food,
which can harm or kill them
. Many animals can become entagled in baloon strings, which can kill them or damage their feet/hands/wings.
Can a helium balloon hit a plane?
A:
Yes
, I have seen several weather balloons while in flight. There have been cases where weather balloons have been struck by airplanes. Usually there is no damage to the aircraft, but occasionally to the weather instruments. It’s a rare occurrence.
Is it illegal to let go of balloons?
In New South Wales, it is
an offence to let go 20 or more helium balloons at once
, with a greater penalty for the release of more than 100 balloons. If you are releasing fewer than 20 balloons at around the same time, they must not have any attachments (like string or plastic discs).
Where do balloons go when let go?
balloons that are released into the air don’t just go away, they either get
snagged on something such as tree branches or electrical wires
, deflate and make their way back down, or rise until they pop and fall back to Earth where they can create a lot of problems.
Is it bad to let go of helium balloons?
All released balloons, including those falsely marketed as “biodegradable latex,” return to Earth as ugly litter. They kill countless animals and cause
dangerous power outages
. Balloons are also a waste of Helium, a finite resource. Balloons can travel thousands of miles and pollute the most remote and pristine places.
Can you send a balloon into space?
A helium-filled balloon can float very high up into the atmosphere, however,
it cannot float up into outer space
. The air in Earth’s atmosphere gets thinner the higher up you go. … This happens at about a height of 20 miles (32 kilometers) above Earth’s surface.
What happen if two balloons rub and place together?
When you rub two things together
you can move the negatively charged electrons from one material to another
. … When you rub both balloons, both end up with negative charge. Similar charges repel so the balloons push away from each other. You can even use one balloon to push the other around!
Why does rubbing two balloons repel?
When rubbing a balloon with a wool cloth, it puts negative charges on the balloon. Negative charges attract to positive charges. … When both balloons are rubbed with the wool cloth,
the both receive negative charges
, so they will repel each other.
Why would a balloon attract your hair without touching it?
Explanation:
Hold the balloon (negatively charged) just above your head so your hair (positively charged) will be attracted to it and stand up on end
. … … The negatively charged balloon repels the electrons of the can so that a positive charge is near the balloon.
What can I use instead of a balloon release?
- Bubbles! Divers love blowing bubbles underwater, and it’s just as fun topside. …
- Confetti alternatives. …
- Flying Wish Paper. …
- Luminarias or reusable luminaries. …
- Origami whales. …
- Plant a tree or flowers.
Can you release balloons at a funeral?
Watching a colorful object drift peacefully towards the sky, perhaps with a note attached, is usually a
welcomed and accepted tradition at funerals
or on days of remembrance. Balloon releases are appealing, the symbolism makes sense.
How high will a party balloon go?
On average weather balloons will ascend for about 90 minutes before bursting. They typically reach
about 60,000 to 105,000 feet
. These numbers can vary due to certain conditions. These conditions include: the time of year, the wind conditions, the weight of your balloon, and how much gas is inside your balloon.
