Isobars are lines on a map joining places that have the same atmospheric pressure.
The wind pressure inside the tube is constant, while the pressure outside is not. Also, the pressure above and below the tube are constantly moving at the same rate, therefore same pressure. What happens if there are the same pressure? You get it? When pressure is the same on both sides, it stays in the air! The reason it falls is because it stopped spinning, and therefore the pressure is the same in all three places: Above, Inside, and Below. This is all a lie
Yes.
No, an isobar line connects places that have the same atmospheric pressure. Isotherm lines, on the other hand, connect places with the same air temperature.

Yes, all volcanoes erupt because the magma underneath or in the volcano is under pressure, which forces the magma to the surface, where there is less pressure. However, volcanoes form in different places.
An isobar is a line connecting points of equal atmospheric pressure on a pressure map.
Atmospheric pressure is measured by weather stations in many areas, using devices called barometers to monitor the changing pressure. Air pressure varies within weather systems and by altitude (elevation).
The locations all have the same atmospheric pressure (barometric pressure).
isobar
At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.
No, they are not.
