Streak
Color is the least reliable physical property for mineral identification because many minerals can have the same color but different properties.
This is the definition of the physical property called streak. The actual color varies depending on the mineral, which is why it is used as an identifying property.
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.
luster
Hardness would be one.
The most useful physical property when classifying a rock is its mineral composition. This includes identifying the specific minerals present in the rock and their relative proportions. By analyzing these properties, geologists can categorize rocks into different types based on their mineral content.
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.
Well yes because you are going to have some of the hardest challenges in your life
Lustre is a physical property, because... Look up a few definitions of "chemical property." In every one you will find that it involves chemical reactions, or changes in the identity of a substance. Lustre (shininess) is a property that can be observed without any chemical changes to the substance, so it can't be a chemical property.
The physical property used to describe how the surface of a mineral reflects light is called luster. Luster describes how light interacts with the surface of a mineral, with terms like metallic, vitreous (glassy), pearly, or dull being commonly used to characterize different types of luster.
The physical property of a mineral that causes it to break with rough or jagged edges
