Question

the resistance of a material to being scratched or having an indentation made is called ______________.

Explanation:

Hardness is defined as a material's resistance to scratching or indentation. It is a fundamental property in materials science, often measured using tests like the Mohs scale (for minerals) or Brinell/ Rockwell/ Vickers tests (for metals and other materials). These tests quantify how well a material can withstand deformation from a harder object pressing against it.

Answer:

Hardness
