Heat Flow - Coupled systems and reversal of processes
Not what you're looking for?
Each of two bodies has a heat capacity given, in the temperature range of interest, by
C = A + BT
• Where A = 8.0 J/K and B = 0.02 J/K2.
If the two bodies are initially at temperatures: T10 = 400.0 K and T20 = 200.0 K, and if they are brought into thermal contact, what is the final temperature and what is the change in entropy?

Solution Summary
The solution examines heat flow. The coupled systems and reversal of processes are analyzed.
Solution Preview
Please see the attachment.
The change in heat is given by:
Where m is the object's mass, c is the object's heat capacity and T is the instantaneous temperature.
Thus, when the object moves from initial temperature Ti to final ...
