Hardness in science refers to the resistance of a material to deformation, indentation, or penetration by means such as abrasion, drilling, impact, scratching, and/or wear, measured by hardness tests such as Brinell, Knoop, Rockwell, or Vickers.

Explanation:

The definition of hardness is the quality or condition of being hard. The cohesion of the particles on the surface of a mineral as determined by its capacity to scratch another or be itself scratched. the Resistance of metal to indentation under a static load or to scratching.
