the properties are the hardness ,luster,streak,floresence.
yes
hardness,
the 5 properties are cleavage hardness luster color streak
physical property
Hardness Streak Luster Color
No, the hardness number of unlike materials does not give a satisfactory basis for comparing their hardness because different materials may have different structures and properties that affect their hardness in ways the hardness number may not fully capture. It is more accurate to use a combination of hardness tests and material properties to make accurate comparisons.
