*Fr.: relation de Boltzmann*
A relation between the → *entropy*
of a given → *state* of a
→ *thermodynamic system* and
the → *probability* of the state:
*S = k* . ln Ω where *S* is the entropy of
the system, *k* is → *Boltzmann's constant*, and
Ω the thermodynamic probability of the state. Boltzmann's relation connects
→ *statistical mechanics* and
→ *thermodynamics*. Ω is the number of possible
→ *microstate*s of the system, and it represents the
→ *randomness* of the system.
The relation also describes the statistical
meaning of the → *second law of thermodynamics*.
This expression has been carved above Boltzmann's name on his tombstone in
Zentralfreihof in Vienna.
Same as → *Boltzmann's entropy formula*. → *Boltzmann's constant*;
→ *relation*. |
