Solids.
When they are the coldest that they can be is when they have the least energy. Absolute Zero is when molecules have no energy and are not moving, but it is impossible to get to that degree.

Solid
The ground state, which is the lowest energy level of an atom, contains the least amount of available energy. Electrons in the ground state have the lowest possible energy and are closest to the nucleus.
Solids have the lowest amount of kinetic energy compared to liquids and gases. This is because the particles in a solid are packed closely together and have limited freedom of movement, resulting in lower energy levels.
The 4th energy level is the lowest that contains and f sub-level
The type of water that contains the lowest amount of chlorine is spring bottled water. Normally it contains no or little chlorine.

Energy
The lowest energy level that has F orbitals is the fourth energy level. The Atomic orbital of any atom only contains 2 electrons.
The principal energy level that contains electrons with the lowest energy is the first energy level (n=1). This level is closest to the nucleus and has the least amount of energy associated with its electrons.
