Rearrange the following sentences to form a coherent paragraph:
1. This occurs because the coolingliquid traps the internal heat, preventing a standard crystal structure from forming.
2. The resulting substance is an amorphous solid, possessing the molecular disorder of a fluid but the physicalrigidity of a crystal.
3. Rapid thermal quenching is the primary method used to bypass the natural crystallization process of certainalloys.
4. Such structural irregularity gives the material unique properties, such as extreme strength and corrosionresistance.
Show answer & explanation
Correct answer: D
Explanation
Correct Answer: 3 → 1 → 2 → 4
Solution:
(3) introduces the topic: rapid thermal quenching prevents normal crystallization.
(1) explains why this happens: the cooling liquid traps internal heat, so crystals cannot form.
(2) states the result: an amorphous solid is formed.
(4) concludes with the effect of this irregular structure: high strength and corrosion resistance.
Correct Paragraph:
Rapid thermal quenching is the primary method used to bypass the natural crystallization process of certain alloys. This occurs because the cooling liquid traps the internal heat, preventing a standard crystal structure from forming. The resulting substance is an amorphous solid, possessing the molecular disorder of a fluid but the physical rigidity of a crystal. Such structural irregularity gives the material unique properties, such as extreme strength and corrosion resistance.
