Question 1 of 10

1. Question
1 point(s)
Based on the definition of materials science, which of the following describes the basic composition of ceramics?
- A liquid mixture containing polymer compounds.
- A solid consisting of inorganic and non-metallic materials.
- A solid consisting of organic and metallic materials.
- A pure metal that has undergone a cold hardening process.
Correct

Incorrect
Question 2 of 10

2. Question
1 point(s)
Why is it difficult or impossible to recycle ceramics through a remelting process like glass?
- Because ceramics have very high heat resistance.
- Because ceramics always react with oxygen when heated.
- Because the ionic bonds in ceramics are too weak to break.
- Because ceramics are too light to be processed in a recycling furnace.
Correct

Question 3 of 10

3. Question
1 point(s)
Ceramics are known to be good electrical insulators. What microscopic factors cause this property?
- The irregular and random arrangement of atoms.
- The absence of free electrons moving in its structure.
- The presence of many free electrons in the atomic structure.
- The ability of atoms to slide past each other.
Correct

Incorrect

- Can shrink with changes in mouth temperature.
- Easily conducts heat from food.
Correct

Incorrect
Question 7 of 10

7. Question
1 point(s)
Refractory ceramics are used to construct containers for pouring molten metal (molds). What are the main characteristics that enable this application?
- Low abrasion resistance.
- Resistance to very high temperatures and thermal shock.
- Transparent properties that allow monitoring of the level of melting.
- The ability to absorb molten metal into its structure.
Correct

Incorrect
Question 8 of 10

8. Question
1 point(s)
Ceramic brake discs in high-performance cars are considered superior to metal alloys because they:
- Have a smooth surface to reduce friction.
- Cheaper and easier to replace.
- Heavier to provide stronger braking momentum.
- Harder, lighter, and resistant to thermal shock.
Correct

Incorrect
