A miner has a bag 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.
Answers
Answer:
you also need the density of sand to predict this.
density of sand is much lower than that of gold so gold will be at the botton will sand floating.
Answer:
The sand will float.
Explanation:
Since sand has a density of 1.6 g/cm3 and gold has a given density of 19.3 g/cm3, the sand will float on top of the molten gold.
Due to the vastly greater density of gold than that of sand, molten gold will have sand floating on top of it because of the disparity in densities.
The melting points of the majority of metals are quite high, not least gold, which becomes a liquid at temperatures above 1,947 degrees Fahrenheit (1,064 degrees Celsius).
The electric field drove the gold atoms to become agitated, which abruptly caused them to lose their ordered structure and rupture the links between them.
It was concluded that the electric field led to the formation of flaws in the layers of the gold's surface, melting the surface.
