What state of matter has the least kinetic energy

The state of matter than has the least internal kinetic energy

(the kinetic energy of all the internal particles

relative to the center of mass of the system),

or the least internal + macrosopic kinetic energy,

is the same state as

"Which state of matter has the least thermal energy?".

(hint: it's not the gaseous state).

However, if you are asking what state of matter has the least macroscopic kinetic energy:

Every state of matter can have systems with zero macroscopic kinetic energy.

So none of them (or perhaps all of them) have the "least" kinetic energy.
