The bulk properties of materials such as their mode of fracture can be related to their____________________?
Correct answer: C. Microstructure
- A. Polymerization
- B. Cleavage
- C. Microstructure
- D. Dislocation
Explanation
Microstructure, including grains, grain boundaries, phases and defects, controls bulk behaviour such as strength and mode of fracture. Students may choose cleavage, but cleavage is a particular type of crystal breaking rather than the internal structure causing the property.

About Quantum Theory and Radiation
Quantum theory treats electromagnetic radiation as packets of energy called photons, with energy proportional to frequency through E equals hf. The topic covers Planck's hypothesis, photon momentum, the photoelectric effect, threshold frequency, work function and wave particle duality, distinguishing quantised energy exchange from classical continuous radiation.
