Abstract : 
I will give a short introduction to non-equilibrium systems and discuss 
whether they can be described by energy or free energy like thermodynamic 
functions. We then ask what happens when two non-equilibrium systems 
are in contact and exchange some quantity, say mass or energy. 
Will the systems eventually evolve to a stationary state where a certain 
intensive thermodynamic variables, like chemical potential or temperature, 
equalizes ? If so, under what conditions ? 

The talk is aimed at general physics audience.
