9. There is only condition where there is no energy, called Absolute zero. |
9. There is only one condition where there is no energy, called Absolute zero. |
10. To be at Absolute zero, there must have a perfect crystal (substance with only one type of atom) and the temperature is 0K.
11. Entropy is the energy of randomness/disorder.
12. A perfect crystal is a substance with only one type of atom. It is needed because if you have more than one type of atom, there is randomness in the substance which requires energy (chemist call it Entropy). So even though you have no energy due to movement (that is what it means to be 0K), you would have energy due to randomness. That is possible since you need no energy to be at Absolute zero.
