In most if not all cases a tornado would be more than 99% air. If a tornado is not lifting any notable amounts of dust or debris might be 99.9995% air by volume while most of the rest is water droplets. It becomes more difficult for tornadoes that contain large amounts of dust and debris, but the vast majority of the volume is still air.
By volume a tornado is probably more than 99% air. The rest is condensation and, in some cases, dust and debris.
A tornado made of air is a tornado. Part of the definition of a tornado is "a violently rotating column of air."
Weight is not something that is measure in a tornado. Even then, the size of a tornado, and therefore the amount of air it contains, varies widely.
No. Winds in a tornado are destructive, and the dust and condensation in the air would preventyou from seeing much.
They aren't. A tornado is a vortex of air, not water. The funnel of a tornado is formed by water droplets, but these droplets only account for a small percentage of the tornado's composition. These droplets form because tornadoes are a product of thunderstorms, meaning there is usually a fair supply of moist air.
Yes. A tornado is pretty much made of air. Although pressure inside a tornado is low it is nowhere near being a complete vacuum.
A tornado creates an area of low pressure. Pressure as much as 100 millibars lower than in the surrounding air have been recorded.
No. A tornado is a vortex of air. There is no air in space.
Air does go up in a tornado and it is cooler than surrounding air due to decompression. However, it is generally fed by warm air. If too much cold air gets into the circulation, the tornado will dissipate.
Air is continuously moving up in a tornado. This means that air surrounding the tornado must move in to replace the rising air.
The air pressure drops sharply in a tornado
No. By definition a tornado is made of air and there is no air in space.
