What do we know about heat from Thermodynamics?

- 1.
- There is ``entropy''
*S*'. In*closed*systems for reversible processes and for irreversible processes (Second Law) - 2.
- Energy is conserved: for reversible processes in
*open*systems (First Law)

**Conjecture:**- These things are
*same:**S*=*S*'. **Meaning of the Boltzmann Constant:**- If we
*defined*entropy as , temperature would have dimension of energy. We measure temperature differently--and must pay for it by adding a constant!

*We can prove all postulates of thermodynamics from statistics!*
