Question 8

Brittle is defined as easily broken.

The term 'brittle' refers to materials that are prone to breaking or shattering under stress rather than bending or deforming. In this context, it accurately captures the nature of glass, which, while hard, can break easily upon impact.

A) Flexible and resilient

This option is incorrect as it describes materials that can bend and absorb stress without breaking. Brittle materials, by definition, lack this ability and instead fracture easily when subjected to force.

B) Easily broken

This option is correct. 'Brittle' specifically characterizes materials that do not deform under stress but rather fracture when that stress exceeds a certain limit. Glass is a prime example of a brittle material, as it can shatter upon impact.

C) Hard and fragile

While this option contains elements of truth, as glass is hard, the term 'fragile' does not fully encapsulate the definition of 'brittle.' Fragility implies a tendency to break, but 'brittle' emphasizes the mechanism of breaking easily without deformation, making this option only partially correct.

D) Tough and sturdy

This option is incorrect because 'tough' and 'sturdy' refer to materials that can withstand stress without breaking, which is the opposite of what 'brittle' signifies. Brittle materials, such as glass, do not possess these qualities.

Conclusion

The correct definition of 'brittle' as 'easily broken' highlights the inherent characteristics of materials like glass. Other options either misrepresent the concept or fail to capture the essence of what makes a material brittle, reinforcing the importance of understanding material properties in various contexts.
