Limit of Entropy as temperature approaching 0 K

[PeterTran1C]

Could someone explain the science/significance of taking the limit of entropy as temperature approaches 0 K. I understand that it is related to the idea of perfectly ordered materials but I am not entirely sure what that means.

[Abel Thomas 2C]

As the temperature approaches 0 K, entropy is decreasing because the number of possible states decreases. Since, the thermal energy is decreasing, you are going from a less ordered system to more ordered system. If the system was at 0 K, or absolute zero, the system would be perfectly ordered. Think of it like cooling a substance. The colder the substance becomes, the smaller the average kinetic energy of the molecules or atoms will be (the less they will move or vibrate).

With this, entropy approaches near zero and such that there is only the vibrational motion of molecules and no movements around. Meaning that we know exactly where molecules are.
