## SNIIX18 Group Title Which equation would you use to find the statistical definition of entropy? one year ago one year ago

1. koushik_ksv Group Title

As far as I know, entropy is defined as $\Delta S = \int\limits_{}^{} dQ/T$

2. Vincent-Lyon.Fr Group Title

$$\Large S=k_B\cdot\ln(\Omega )$$

you dont know how hard it was for me to draw this :)

5. koushik_ksv Group Title

@vincent-lyon.Fr , can you explain me your equation

6. koushik_ksv Group Title

It is B, just now read the https://en.wikipedia.org/wiki/Entropy#Statistical_mechanics. See the first definition and then the statistical mechanics link in the page.
