Re: Heat through an adiabatic wall?



It is NOT true that "anything which increases entropy is heat". This can
be read as true , ie: dS=dQ/T, only for a REVERSIBLE process (not
necessarily the actual process under consideration) connecting the actual
end states of the system under consideration.

Subject: Heat through an adiabatic wall?


I have been preparing to teach thermo for the first time this spring and
have learned a lot mostly lurking on this list. However, I have come to
a
bit of a paradox having to do with the definitions of heat (Q) and
adiabatic. Let me see if I can state this well.
