- Named After
- Walther Nernst

- S entropy of a perfect crystal · T absolute temperature
- Year

Significance
As temperature approaches absolute zero, entropy approaches a constant floor — zero for a perfect crystal. Consequence: absolute zero itself can be approached but never reached, no matter how clever the refrigerator.
