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.
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.
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.
As you fill a balloon with air, the rubber stretches to accommodate the increased volume of air inside. The pressure inside the balloon increases, causing it to expand and inflate. If you continue to fill it with more air, eventually the rubber may reach its limit and the balloon could burst.
If the pressure around the balloon decreases, the air inside the balloon will expand to fill the available space. This will cause the balloon to inflate or expand.
Yes, when you fill a balloon with air, you are displacing the air that was originally inside the balloon with the new air. This is an example of the principle of displacement.
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.
You can fill a balloon with helium, air, or water.
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.
Fill the balloon with a gas which is lighter than air: helium, for example.
