What best describes the force of atmospheric pressure on a blimp?
An air compressor blowing gasses into the blimp is what causes the air pressure in the blimp. These gases are lighter than air.
Element used in the goodyear blimp and other dirigibles?
The element that is used in the Goodyear blimp and other dirigibles is helium. This gas is lighter than air and causes the blimp to rise.
What causes the air pressure inside an inflated balloon?
The elastic contraction of the rubber in the balloon's membrane causes the pressure in the air inside an inflated balloon. When you inflate a balloon, you have to expand the latex of the balloon, which stretches when filled with air from a pressure of 760 mm Hg to as high as 840 (about 10% higher than standard atmospheric pressure). If you inflate a non-elastic mylar balloon, it takes no effort: the air inside is at the same pressure as the air outside.
What causes air to rush into a tornado?
There is very Low Pressure inside a tornado. Air naturally tends to move towards and area of low pressure.
Is a engine essential to keeping a blimp in the air?
No. helium gas inside the blimp keeps it aloft. Just like a helium makes balloons fly!!
Why do tin cans get crushed if cooled after heated and closing is mouth?
Assuming the can can be sealed. When the can is heated the air inside it expands. If the can is then sealed and allowed to cool the air inside contracts which causes the pressure inside to drop. Because the outside air pressure is now greater it crushes the can.
Are engines essential to keep blimp in the air?
No. helium gas inside the blimp keeps it aloft. Just like a helium makes balloons fly!!
Why does a hot air balloon when the air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
Why does a hot air balloon rise when the air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
Why does a hot air balloon rises when air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
What generally happens to atmospheric pressure on a windy day?
On a windy day atmospheric pressure decreases because the higher the wind velocity, the lower the air pressure, or atmospheric pressure. This is how chimneys work, the air that moves above the chimney causes low air pressure because of the high wind velocity compared the velocity of the air inside a house. The air inside the house goes towards the low air pressure and takes the smoke with it.
Is the pressure of a balloon greater on the inside or outside?
It's greater on the outside until it rises to a point in the atmosphere where the air is very thing. At that point, the pressure inside the balloon is greater which causes it to pop.
