This video explains, Do Electrons Stop Moving at Absolute Zero Temperature and What Happens at Absolute Zero Temperature. This video also explains the Heisenberg uncertainty principle in quantum mechanics.
Do electrons stop moving at absolute zero temperature? The answer is- No.
Electrons inside an atom continue to move even at the lowest possible temperature known as the absolute zero temperature.
It's value is -273 degree Celsius or 0K.
Actually it is the random motion of atoms and molecules in the matter that is responsible for its temperature not the motion of electrons in the atom.
So at the absolute zero temperature atoms and molecules come to rest but not the electrons.
As it's not possible to slow down the motion of atoms which are already at rest, so we cannot get lower temperature than the absolute zero.
According to the Heisenberg's uncertainty principle in quantum physics, it's not possible to measure the exact position and momentum of a particle at the same time.
So if electrons come to rest we would know their exact position and exact momentum which is zero for rest.
But it's not possible according to the uncertainty principle.
It means electrons keep moving even at the absolute zero temperature.
