What's the problem? Energy conservation laws are applicable in any inertial system, but you can not "jump" from one system to another so easily. Energy is not a constant value which does not depend on choice of system.

Gas pressure ~1 Torr is not the high quality vacuum :) It's quite bad vacuum. As to the question - it depends on the type of liquid and temperature. For example, mercury can exist as a liquid at the room temperature and pressure ~10^-2 torr.

Parallel circuit will drain faster, due to the lower resistance.

I think that it is impossible to remove air with the use of sound waves. Air depression in a sound wave is quite negligible. But may be shock waves can be used for air removing...

AFAIR, it might be supposed that bulk charge within sphere is equal to the point charge Q=(4/3)*Pi*(R^3)*ro placed into the center of sphere.

Plasma potential acts as potential barrier for electrons confined in plasma. So what will happen if the electron energy is suddenly arisen, for example, by an order of magnitude? Electrons will overcome the potential barrier and negative charge located on the walls will increase rapidly, so...

Plasma temperature does not depend on the distance between charged particles. Very hot plasma with low density of charged particles can be obtained, and high-density cold plasma can be obtained too.
