Plasma
I'll take a guess and say plasma. Someone check me on that.
Plasma's are the most energetic states we have discovered but the answer you are probably looking for is when the matter is in a gaseous state, that is when the atoms have dissociated from each other almost completely. But in plasma the particles that make up an atom have dissociated.
Liquid State
Yes, particularly if you add thermal energy. At its least energetic, matter is in the solid state. Add some more energy, it transitions to the liquid state. Then more and it's a gas. Finally, at its most energetic, it is in the plasma state.
gjknm,
The one with the least heat, therefore, solids.

Plasma
No. A vacuum is a point in space where there is literally nothing - no dust/oxygen/water particles. Ie. it contains absolutely no matter whatsoever, and therefore by definition, is not a state of matter.
No, the flame itself contains a mixture of gas, plasma, and often small solid particles.
Definitely solid, which in this state molecules of matter is bonded with strongest intermolecular force (comparing to th eother state).
Particles that make up matter are in a state of constant motion.
Gases seems like the most obvious answer because of the energetic particles. However you may find it advisable to double check this answer befor proceeding further in this subject xxx
By how dense the state of matter
The state of matter in which particles are loosely connected is gaseous state
As the space changes between the particles, so does the state of matter.
