Which of the following is NOT a major characteristic used to identify minerals? a. hardness c. density b. magnetism d. luster Please select the best answer from the choices provided A B C D
Answers
Answer: d. Luster
Explanation:
The term hardness defines the strength of the metal.
The density defines heaviness of the metal.
The magnetism defines the magnetic property of the object.
The term luster defines the polished surface and shining capacity of the metal.
Illustration:
While making a metal component or a machine, one should consider the strength and the weight of the component because these two property will affect the efficiency of the component.
The magnetism is very important because we cannot use the magnetic material in certain machines and vehicles.
Thus, the hardness is the least bothered character when manufacturing a metallic product because even the surface is not shiny or polished, it could be grinded or buffed to increase the luster.
