Well yes because you are going to have some of the hardest challenges in your life
Hardness would be one.
physical property
Hardness is a more reliable property for identifying minerals because it is a physical characteristic that does not change with external factors. Magnetism, on the other hand, can be influenced by the presence of other magnetic materials in the environment, making it less consistent for mineral identification.
physical property
The most diagnostic physical property of a mineral is its hardness, which is measured on the Mohs scale. Hardness indicates how resistant a mineral is to scratching and can help distinguish between different minerals. For example, talc is the softest mineral on the scale (1), while diamond is the hardest (10). Other important properties include color, luster, and streak, but hardness is often the most reliable for identification.
Hardness
You could test for the property of hardness by seeing which mineral scratches the other. The mineral that scratches the other is the harder one.
The hardness of diamond is a physical property of the diamond. The statement is also untrue as diamond is only the hardest known mineral, not the hardest known substance.
The hardness of a diamond is a physical property because it pertains to the material's ability to withstand scratching and abrasion. It is determined by the structural arrangement of its atoms and the strength of its covalent bonds.
Mineral hardness measures the resistance of a mineral to scratching or abrasion. It is determined by the ability of a mineral to scratch another mineral or be scratched by it, as defined by the Mohs scale of hardness.
Hardness measures a mineral's resistance to being scratched.
The most reliable physical property to identify a mineral is its chemical composition. This is because each mineral has a unique combination of elements that make up its structure, which can be determined through chemical testing. Additionally, properties like hardness, cleavage, and specific gravity can also aid in identifying minerals.
