If I have and object at a different temperature than the thermal/heat reservoir (whatever it's called) an heat flow will take place. If I write the entropy balance for the thermal reservoir it will be:
##\frac {dS} {dt} = \frac {\dot Q} T + \dot S_{gen}##
Now I remember something my professor told me a year ago (I could never fully understand it and it keeps coming back to mind),
from his book (I tried to translate it correctly):
can someone please explain it to me?
Thanks
Ric

Now I remember something my professor told me a year ago (I could never fully understand it and it keeps coming back to mind),
from his book (I tried to translate it correctly):
the rate at which entropy is generated within the system (##S_{gen}##) is always zero because, since the temperature is uniform ad constant, the effect of the heat flow is the same for every temperature of the object it's exchanging heat with.
can someone please explain it to me?
Thanks
