Question
- Plot DSa and DSw as functions of Tw on a single graph.
- Plot DSsys [DSsys = DSa +DSw] as functions of Tw on a second graph.
![Consider a 6.0 kg block of pure aluminum and 1.0 kg of water in an insulated container. Initially, the
aluminum is at 55°C and the water at 5°C. The aluminum is placed into the water and eventually comes
to an equilibrium temperature with the water.
1) Use conservation of energy to find the equilibrium temperature of the water and the aluminum
2) Find the temperature of the aluminum, Ta, as a function of the temperature of the water, Tw.
That is: find the functional relationship T3= f(Tw).
3) Find the change in entropy for the water, as a function of Tw [ASy = f(Tw)]
4) Find the change in entropy for the aluminum, as a function of T. [AS, = f(T.)]. as well as a
function of Tw, [AS, = f(Tw)].](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F802a7042-dca4-4c16-8808-146e7633f86e%2Fc380997f-46a1-4a86-8085-7f2d369fbbf6%2Fih7vi0i_processed.png&w=3840&q=75)
