Match the term to the correct description or definition: Characteristic or condition of relative fragility, easily damaged by physical stress or abrasion.

The term that matches the description "Characteristic or condition of relative fragility, easily damaged by physical stress or abrasion" is Brittleness.

Brittleness refers to a material's tendency to fracture or break easily when subjected to stress, rather than deforming or bending. This characteristic is often observed in materials that lack the ability to absorb energy and deform plastically—such as glass, ceramics, and certain hard plastics. When a brittle material is under stress, it reaches a limit where it can no longer withstand the force applied, causing it to break suddenly without significant deformation. Understanding brittleness is crucial in fields such as materials science and engineering, where selecting appropriate materials for specific applications is essential to ensure safety and durability.
