A The mercury will change temperature at a much faster rate under the same heating conditions. <span>B The two metal samples will change temperature at about the same rate. </span> <span>C The gold would float if placed in the mercury. </span> <span>D The gold would sink to the bottom if placed in the mercury. </span> <span>a = false, it will take 0.031 cal to raise 1g Au 1degree while it will take 0.033 cal to raise 1g Hg 1 degree so, although Au will heat up faster, it will not be discernably faster so... b = true c = false, Au density > Hg d = true</span>
