If you accept that the 2nd law of thermo tells you that the
[tex] Work_{net} = Q_{in} - Q_{out} [/tex]
it's easy to see why 2 adiabatic processes cannot cross on a PV diagram when connected by an isothermal process.
however, why is the 2nd law true without taking a statistical approach?
Why must we have heat flow in order to get work out of an engine?
