Which of the following best defines 'softness' in materials?

• A. Ability to Conduct Electricity
• B. Tendency to Bend Under Stress
• C. Ability to be Scratched or Indented
• D. Resistance to Compression

Answer: (C)

The concept of 'softness' in materials is primarily defined by their ability to be scratched or indented. This characteristic indicates how easily a material can be deformed or penetrated by another object, reflecting its relative hardness. A softer material will show visible marks or impressions when subjected to an external force, such as a scratch from a harder object. This property is crucial in materials science, industrial applications, and manufacturing processes where understanding the behavior of materials under different conditions influences design and functionality. In contrast, abilities related to conductivity, bending, or resistance to compression measure different aspects of material behavior. For instance, conductivity pertains to electrical properties rather than mechanical and physical characteristics. Similarly, the tendency to bend under stress speaks to ductility and flexibility, while resistance to compression refers to a material's capacity to withstand compressive forces without failure. These aspects do not define softness but instead contribute to a material's overall mechanical profile. Hence, the ability to be scratched or indented captures the essence of what softness entails in the context of material science.
