Death is the most probable thing
Objects inside a tornado are called debris.
It becomes a tornado, obviously.
If two tornadoes meet, they will merge to form one tornado.
The pressure inside a tornado is much lower than it is outside.
The parent circulation of the tornado, called a mesocyclone, keeps a tornado going.
No. The pressure drop inside a tornado is not large enough for this to happen. Tornadoes tear houses apart with the power of their wind.
That is not known. Not enough measurements have been taken from inside a tornado.
No, it can not happen. You will always need a cloud to form a tornado. The kind of cloud that a tornado uses is a cumulonimbus cloud.
A tornado can hit a house, but cannot happen indoors.
Yes. There is plenty of air inside a tornado, even in the "eye." The pressure is low inside a tornado but certainly not an actual vacuum.
in tornado alley which is in Texas and states close to it
No most tornado strikes happen in the Midwest in tornado valley but they can happen any where but mainly in middle March to early October
There is not such thing as a "chemical tornado" a tornado is the result of thermodynamic physical processes.
When two tornadoes meet they merge to form a larger tornado. This is an unusual occurrence, but when it does happen it usually involves a large tornado absorbing a smaller one.
The air pressure inside a tornado is very low.
Considering that you shouldn't go outside during a tornado, yes. You are much safer inside.
Air density inside a tornado is about 5-10% less than that of the air surrounding it.
