It needs to be open at the bottom to get heat from the burners into the balloon to warm up the air and decrease its density. If you sealed it off, eventually heat exchange through the fabric of the balloon would could the air off enough that the balloon would no longer be bouyant and it would lose altitute.
The balloon would get larger as the air pressure outside it dropped. At some height, the balloon would get large enough to burst.
what are the charicteristics about of a high pressure system
If a hot air balloon were on the moon, it would not function as it does on Earth. The moon has no atmosphere, which means there is no air to heat and create lift. Consequently, the balloon would remain deflated and grounded, as there would be no buoyant force to support it. Additionally, the moon's lower gravity would not provide the necessary conditions for a hot air balloon to operate effectively.
After you hit a certain altitude, the air would become so thin, it would starve the flame making the balloon rise of oxygen, the flame would go out, and the balloon would come plummeting back down to earth
Hot air balloons work by heating the air inside the balloon envelope using a propane burner. When the air inside the balloon is heated, it becomes lighter and less dense than the surrounding air, causing the balloon to rise. The envelope of the balloon is sealed, which allows the hot air to be trapped inside and keep the balloon aloft.
Cooling the air inside a sealed balloon will cause the air particles to slow down and lose energy, resulting in a decrease in pressure. As a result, the balloon will shrink in size due to the decrease in pressure exerted by the air particles on the balloon walls.
the balloon's volume would decrease!!!
the balloon's volume would decrease!!!
it wold pop.
The Hot air balloon wouldnt fly strait
You would be like a balloon with no air,useless!!
The balloon would get larger as the air pressure outside it dropped. At some height, the balloon would get large enough to burst.
Putting an air-filled balloon in a refrigerator will cause it to shrink.
The balloon would shrink in size as the air inside cools and contracts. This is because gases, like the air in the balloon, contract when they are cooled and expand when they are warmed.
As it gets colder the air molecules move closer together and the balloon deflates.
When the air inside a balloon cools, it will also contract, therefore the balloon will partially deflate.
when a body is put in a sealed bag then it would remain as such .......... nothing would happen to that as there is no air and moisture so that any microbial growth can occur...........
