**Unformatted text preview: **a) Which diagram (A or B) represents copper, and which represents gold? Give two reasons justifying your answer. b) Two blocks of metal, one containing a mole of copper atoms, the other containing a mole of gold atoms, are initially at a very low temperature, close to 0 K. Suppose that one joule of energy were added to each block. Now which block has the greater entropy? Explain your reasoning clearly. Do not skip any steps in reasoning – be explicit about each inference. c) Which block now has the higher temperature? Explain. Ground state E E 1 E 2 E 3 E 4 Ground state E E 5 E 6 E 7 E 1 E 2 E 3 E 4 A B...
