Solids.
The solid phase state has the lowest kinetic energy because the particles are closely packed together and have the least amount of movement and vibrational energy compared to the liquid and gas phases.

Energy
Phase energy refers to the energy associated with the phase of a material, such as liquid, solid, or gas. It represents the energy required to change the phase of a substance, for example, to melt ice into water or boil water into steam. Phase energy is a critical concept in thermodynamics and plays a key role in understanding phase transitions.
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.
Atoms
gas
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.
