Which of the following is NOT a type of crystal structure?

  1. Cubic

  2. Tetragonal

  3. Orthorhombic

  4. Amorphous


Correct Option: D
Explanation:

Amorphous materials do not have a regular crystal structure, unlike cubic, tetragonal, and orthorhombic structures.

The mechanical property of a material that describes its resistance to permanent deformation is called:

  1. Hardness

  2. Toughness

  3. Elasticity

  4. Plasticity


Correct Option: A
Explanation:

Hardness is the measure of a material's resistance to permanent deformation, while toughness, elasticity, and plasticity describe other mechanical properties.

Which of the following materials is known for its high electrical conductivity?

  1. Copper

  2. Aluminum

  3. Iron

  4. Steel


Correct Option: A
Explanation:

Copper is known for its excellent electrical conductivity, making it widely used in electrical applications.

The ability of a material to absorb and store energy when deformed and release it upon unloading is known as:

  1. Resilience

  2. Toughness

  3. Elasticity

  4. Plasticity


Correct Option: A
Explanation:

Resilience is the property of a material to store and release energy during deformation and unloading.

Which of the following is NOT a type of composite material?

  1. Fiber-reinforced polymers

  2. Metal-matrix composites

  3. Ceramic-matrix composites

  4. Homogeneous materials


Correct Option: D
Explanation:

Homogeneous materials are not composites, as they do not consist of two or more distinct phases.

The phenomenon where a material undergoes a sudden change in its properties when heated or cooled is known as:

  1. Phase transition

  2. Melting

  3. Evaporation

  4. Condensation


Correct Option: A
Explanation:

Phase transition is the change in the physical state or structure of a material due to changes in temperature or pressure.

The ability of a material to resist wear and abrasion is known as:

  1. Hardness

  2. Toughness

  3. Wear resistance

  4. Corrosion resistance


Correct Option: C
Explanation:

Wear resistance is the property of a material to withstand wear and abrasion, while hardness, toughness, and corrosion resistance describe other material properties.

Which of the following materials is known for its high thermal conductivity?

  1. Diamond

  2. Copper

  3. Aluminum

  4. Steel


Correct Option: A
Explanation:

Diamond has the highest thermal conductivity among all known materials, making it an excellent conductor of heat.

The process of heating a material to a high temperature and then cooling it rapidly to obtain a desired microstructure is called:

  1. Annealing

  2. Quenching

  3. Tempering

  4. Normalizing


Correct Option: B
Explanation:

Quenching involves rapid cooling of a material to obtain a desired microstructure and properties.

Which of the following is NOT a type of polymer?

  1. Thermoplastics

  2. Thermosets

  3. Elastomers

  4. Metals


Correct Option: D
Explanation:

Metals are not polymers, as they do not consist of long chains of repeating units like polymers.

The ability of a material to resist fracture when subjected to a load is known as:

  1. Strength

  2. Toughness

  3. Hardness

  4. Elasticity


Correct Option: B
Explanation:

Toughness is the property of a material to resist fracture and absorb energy before breaking.

Which of the following materials is known for its high strength-to-weight ratio?

  1. Steel

  2. Aluminum

  3. Titanium

  4. Concrete


Correct Option: C
Explanation:

Titanium has a high strength-to-weight ratio, making it a lightweight and strong material.

The ability of a material to return to its original shape after being deformed is known as:

  1. Elasticity

  2. Plasticity

  3. Resilience

  4. Toughness


Correct Option: A
Explanation:

Elasticity is the property of a material to return to its original shape after being deformed.

Which of the following materials is known for its high corrosion resistance?

  1. Stainless steel

  2. Aluminum

  3. Copper

  4. Iron


Correct Option: A
Explanation:

Stainless steel is known for its high corrosion resistance due to the presence of chromium.

The process of joining two or more pieces of metal by melting and fusing them together is called:

  1. Welding

  2. Brazing

  3. Soldering

  4. Adhesive bonding


Correct Option: A
Explanation:

Welding involves melting and fusing metal pieces together to create a permanent joint.
