One end of a metal rod is in contact with a thermal reservoir at 731 K, and the other end is in contact with a thermal reservoir at 107 K. The rod and reservoirs make up a closed system. If 6450 J are conducted from one end of the rod to the other uniformly (no change in temperature along the rod) ...

a) ... what is the change in entropy of the 731-K reservoir?

b) ... what is the change in entropy of the 107-K reservoir?

c) ... what is the change in entropy of the rod?

d) ... what is the change in entropy of the system?

    Don't you ever shyow your work, maria?
    When you do, I will be glad to help.

    Start with the definition of entropy change, (Heat added)/T
