no, when we blow a balloon we actually fill carbon dioxide from aor lungs into it,...so the proportion is not same,there is more carbon dioxide in the balloon as compared to its surroundings as the normal air contains approx 0.4% of carbon dioxide and different percentages of other gasses.
No. Helium is lighter than air
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
yes
I would say an air filled balloon if you fill it with just plain air. I am basing this on the principle of osmosis and diffusion. A substance such as a gas will travel from an area of increased concentration, such as a balloon filled with helium, to an area od decreased concentration, such as the room the balloon is in. If you fill the balloon with air identicle to that in the surrounding room it negates diffusion.
alveoli
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
air
Putting an air-filled balloon in a refrigerator will cause it to shrink.
No it decreases
A water balloon is filled with water, and other balloons are filled with air or helium.
The duration an air-filled balloon stays inflated can vary based on factors such as the quality of the balloon, temperature, and air pressure. Under normal conditions, an air-filled balloon can stay inflated for several days to a week before starting to deflate.
The balloon expands.
No. Helium is lighter than air
When you squeeze an air-filled balloon, the air inside gets compressed, causing an increase in pressure. If the pressure becomes too high, the balloon may pop.
A typical hot air balloon is filled with the same air we breath.
Yes, sound can pass through a balloon filled with air. The sound waves will travel through the air inside the balloon and vibrate the balloon's surface, creating sound on the other side.
