Below are the choices:

A The mercury will change temperature at a much faster rate under the same heating conditions.

B The two metal samples will change temperature at about the same rate.

C The gold would float if placed in the mercury.

D The gold would sink to the bottom if placed in the mercury.

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
