A 15 cm\(^3\) block of gold weighs 2.8 N. It is carefully submerged in a tank of mercury. One cm\(^3\) of mercury weighs 0.13 N.

a. Will the mercury be displaced by the gold?

b. Will the gold sink or float in the mercury?

Asked by arosebud14

Answer (2)

The density of gold is 2.8 N / 15 = 0.18 units The density of mercury is 0.13/1 = 0.13 units
Since the density of gold is more than density of mercury, it will sink. Since the gold will sink, it will displace mercury, but less than its own volume

The gold block will displace mercury as it is submerged because it has a greater density than mercury. Furthermore, the gold will sink in the mercury, as its density is higher than that of mercury. Thus, it will not float but displace an equal volume of mercury equal to its own volume.
