Balloons are filled with gas (such as helium), or a mixture of gasses (such as air) or hot gasses (such as hot air).
Helium.
When you fill a balloon with air, the air molecules displace the surrounding space inside the balloon, causing the balloon to expand and stretch. The pressure of the air inside the balloon exceeds the pressure outside, creating tension in the balloon material, which keeps it inflated.
When helium is used to fill a balloon, it expands to fill the space inside the balloon due to its low density. The helium gas takes the shape of the balloon because it moves and distributes evenly throughout the balloon's interior.
It typically takes about 0.5 pounds of helium to fill a 12-inch latex balloon.
Filling a balloon with pure oxygen can be dangerous as oxygen accelerates combustion. It can create a highly flammable environment, increasing the risk of fire or explosion. It is not recommended to fill balloons with pure oxygen.
Helium gas is lighter than air and hence balloons filled with helium will float in air.
I personally fill a balloon with my breath, the balloons I buy are already filled with helium.
A balloon or a tire can both be filled with air.
When you fill a balloon with air, the air molecules displace the surrounding space inside the balloon, causing the balloon to expand and stretch. The pressure of the air inside the balloon exceeds the pressure outside, creating tension in the balloon material, which keeps it inflated.
The air in the balloon will have a difficult time expanding to fill the bottle because the bottle is already filled with air at atmospheric pressure, which creates resistance. The pressure inside the balloon needs to overcome the pressure inside the bottle in order for the balloon to expand and fill the bottle.
You fill up the balloon by asking G for the super helium.
When helium is used to fill a balloon, it expands to fill the space inside the balloon due to its low density. The helium gas takes the shape of the balloon because it moves and distributes evenly throughout the balloon's interior.
The air inside a balloon takes the shape of the balloon itself. It expands to fill the space within the balloon, conforming to its size and shape.
air?
When you inflate a balloon, even on land, you pinch the mouth of the balloon shut to stop air escaping once you have run out of air. You can do the same thing underwater. Take a breath, dive under, and blow into the balloon, and pinch it when you run out of air. You could also use a snorkel, but you will need to make sure you leave enough air in your lungs to blow water out of the snorkel.
When you fill a balloon with steam and put it in the refrigerator, the steam will condense back into water droplets, causing the balloon to shrink as the gas inside loses volume. The cooling of the gas molecules in the balloon will also decrease their kinetic energy, leading to a decrease in pressure inside the balloon.
hot balloon will pop first
Fill the balloon with a gas which is lighter than air: helium, for example.
