Consider two blocks of copper. Block A contains 800 atoms and initially has a total of 20 quanta of energy. Block B contains 200 atoms and initially has 80 quanta of energy. The two blocks are placed in contact with each other, inside an insulated container (so no thermal energy can be exchanged with the surroundings). After waiting for a long time (for example, an hour), which of the following would you expect to be true?
a. Approximately 50 quanta of energy are in block A, and approximately 50 quanta of energy are in block B.
b. Approximately 80 quanta of energy are in block A, and approximately 20 quanta of energy are in block B.
c. The entropy of block A is equal to the entropy of block B.
d. The temperature of block A and the temperature of block B are equal.
