Best Viewed With GFS!Orders of magnitude (entropy)
From Wikipedia, the free encyclopedia
The following list shows different orders of magnitude of entropy.
| Factor (J K−1) | Value | Item |
|---|---|---|
| 10−24 | 9.5699×10−24 J K−1 | entropy equivalent of one bit of information, = k ln 21 |
| 1 | 5.74 J K−1 | standard entropy of 1 mole of graphite2 |
| 1033 | ≈ 1035 J K−1 | entropy of the Sun (given as ≈ 1042 erg K−1 in Bekenstein (1973))3 |
| 1054 | 1.5 × 1054 J K−1 | entropy of a black hole of one solar mass (given as ≈ 1060 erg K−1 in Bekenstein (1973))3 |
| 1081 | 4.3 × 1081 J K−1 | one estimate of the theoretical maximum entropy of the universe45 |
