Question

A miner has a bag of containing a mixture of gold dust and sand. Gold has a density of 19.3 g/cm. He heats the mixture until the gold melts. Predict whether the sand will float on top of the molten gold.

Answer 1

Answer:

No

Explanation:

Answer 2

The sand will float on top of the molten gold.

• Since density of gold as given is 19.3 g/cm3 and the density of sand is 1.6 gm/cm^3.

• The density of gold is much greater than that of the sand, therefore the molten gold will have floating sand on top of it due to the difference in density.
