Answer 1

Answer:The properties of the Hardness are:

• Hardness is a physical property
• Hardness is indicative of the strength of chemical bonds between elements.
• Diamond can scratch quartz Explanation:

Hardness is defined as resistance offered by a material when subjected to any kind of mechanical effort.It is a physical property

Hardness of a materiel indicates its strength that strength of its chemical bond between the atoms and their arrangement in space.

Mohs scale is a scale which measures the hardness of the materiel from 1 to 10. Materiel with higher Mohs scale number will able to scratch materiel with lower Mohs scale score.
