no, it is under extreme pressure
no it is under high pressure
It is under lower pressure, however, it is under pressure enough to compress it into a liquid.
The outer core is liquid. Its pressure is low enough and its temperature high enough for it to melt. The inner core is solid. Both its pressure and temperature are higher than the outer core, but the increased pressure overwhelms the increased temperature, keeping the inner core from melting.
I think you are correct. The general scientific consensus is that the inner core is under extreme temperature (same as the surface of the sun) and pressure and therefore must be a solid hunk of iron (100km across or something), but I think they've all got it wrong. The net gravity should be zero in all directions at the core and therefore, I would expect the core to be a vacuum, probably not nearly as hot as believed and probably low pressure. I have yet to see a reasonable explanation of why it is thought to be high pressure anyway.

not all solid, the outer core is of low viscosity
low pressure port is located by the evaporator/heater core under the hood, you have to look good because they have done a very good job of hiding it from us.
the pressure under the train needs to be low because it has a big area
A solution under high pressure will have more gas dissolved in it than one under low pressure.
the solution with higher pressure would have more gas in it that the one with low pressure.
A solution under a high pressure
During low pressure, and low temperature conditions
