Simply put, the weather balloon is a lighter-than-air vehicle or aerosonde that provides lift to an instrument package to get it to altitude. The instruments thus situated can collect data which, when combined with other information from both similar and different sources, can be used to assess current conditions, and, as an extension, to forecast weather.
No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.
Raising the air temperature inside the envelope makes it lighter than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water
A balloon expands when exposed to heat as the air particles inside it move faster, causing the balloon to inflate. Conversely, a balloon shrinks in cold temperatures as the air particles slow down, reducing the size of the balloon.
Yes you can if all conditions were perfect. By that I mean that the bottle would have to be a near perfect vacuum by sucking out the air from the bottle with the straw. The vacated air from the bottle would be replaced by the baloon stretching to fill the space left by the air. You would have no need to blow into the baloon as the vacuum would do the work for you.
Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. In a hot air balloon, the heated air inside the balloon is less dense than the cooler air outside, creating a buoyant force that lifts the balloon. This principle allows the hot air balloon to float in the air by displacing enough air to lift its weight.
It is the same as the air we breath, the only difference is that it has been heated, hot air rises above cold air and thats what lifts the baloon.
Hot air balloons fly by heating the air within the balloon envelope, which causes it to become less dense than the surrounding air. This difference in density creates lift, allowing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can make the balloon ascend or descend.
Your stomach is like a baloon in the way that it expands with air in it.
Because hot air rises, so if there is hot air inside the baloon, the balloon will be compelled to ride because the air pushes against the balloon upward, and, long story short, the air wins. Hope this helped.
The earths atmosphere is denser than the helium found in a baloon therefore the baloon is lighter and is lifted above the denser air located in earths atmosphere. Which is why if you just blow up a baloon with air from your lungs it does not float. It would be the same density as the air outside of the baloon.
You must personaly know Mau Ze Dounge and have at least 75million dollars and own a hot air baloon.

A company called Above the Clouds Inc. offers hot air ballon rides in New York. You can find them online at abovetheclouds.com.
Take a paper bag, and a hair dryer and go outside in a chill morning....fill the paper bag with warm air from the hairdryer and release, it will fly away. Do the same when its hot outside, it will not work.... The thing is that a Hot Air Baloon needs chill air to be able to fly since the hot air are working as thrust....
Because Helium is less dense than air, and CO2, I assume is more dense
The law is called Law of Buoyancy, matter with less density tries to raise above the matter with high density. When air is heated, the volume increases and density decreases. Since the air around the ballon is at a lower temperature and the density is higher, the air in the baloon tries to move up thus lifting the baloon.
