Let there be a hollow pole standing on the surface of the Earth and is long enough to go beyond the atmosphere, the upper end of the pole is open to empty space (vacuum) and at the lower end of pole there are holes for air to pass. Will the air start moving inside the pole and travel across it through space? or nothing will happen?
Dear student,
Pressure at any point on the earth's surface will be same at all the points. So if you place a hypothetical pole that can go beyond the atmosphere, the lower end of the pole will also have the same pressure on it. So, the air will enter in the pole up to a certain height so that the lowest point (on the earth surface) has the same pressure on it. Hence there is no chance to escape any of the portion of air in space.
