Why is pressure low under a train?
the pressure under the train needs to be low because it has a big area
What force is created by high pressure under a wing and low pressure above a wing?
Lift
What type of air pressure creates a tornado?
Tornadoes form under conditions of low pressure
Why it is dangerous to stand near a railway line when a fast train is passing by?
Probably for the same reason you don't want to hang out next to a sinking ship or stand under a passing airplane - the air or water nearby is being pushed aside and creating a vortex. The air disturbance along with the ground vibrations may cause you to lose your balance and possibly fall into the passing train and maybe die. When a train is moving at a high speed; the velocity of air increases; according to bernoulli' s theorem, as the velocity increases, the pressure decreases. Thus the place where we are standing is a region of high pressure and the place where the train is moving is a region of low pressure. We are pulled from a region of high to a region of low pressure.
Why would the top of a mountain have a low air pressure?
The higher you are in the atmosphere, the lower the air pressure. Seeing that the top of a mountain is quite high, the air pressure is low; the air is thinner. This is why you need oxygen tanks to reach the top of Mount Everest

What are the three things that help keep the pressure low under a train?
There is nothing that is specifically designed to keep the air pressure low under a train. A train is kept on the tracks by gravity, nothing more.
How do you keep the pressure under a train low?
because if not then you have friction and friction causes massive problems

Is the outer core is under low pressure?
no, it is under extreme pressure
Which solution will have more gas dissolved in it a solution under high pressure or 1 under low pressure?
A solution under high pressure will have more gas dissolved in it than one under low pressure.
What explodes under low pressure?
Anything expandable/flexible will expand under low pressure. but in order for it to explode I guess you need to contain it within a relatively thin container made of stronger material. eg. balloon
Is earth's outer core under low pressure?
no it is under high pressure
Which solution will have more gas dissolved in it solution under high pressure or one under low pressure?
the solution with higher pressure would have more gas in it that the one with low pressure.
Which solution will have more gas dissolved in it a solution under high-pressure or under low pressure?
A solution under a high pressure
Earthes outer core us under low pressure?
It is under lower pressure, however, it is under pressure enough to compress it into a liquid.
Under which conditions does a real gas behave most like an ideal gas?
During low pressure, and low temperature conditions
