Calculating entropy generation of a process

  1. Nov 29, 2015 #1
    Lets say we have T1. From a reservoir 4000K, Q is added and that makes the temperature T2.
    How do we calculate the entropy generation in a process like that?

    Isn't it Sgen=S2 - S1 - (Q/T)

    But which temperature we will use in the (Q/T)? T1, T2 or 4000K?
