T-Level 2.3 Materials science principles

What property measures a material's ability to deform under tensile stress without breaking?

• Conductivity

• Ductility

• Compressive strength

• Durability

Which of the following is NOT a factor that contributes to the degradation of materials?

• Chemical composition

• Environmental conditions

• Ductility

• Mechanical stress

What is the ability of a material to be hammered or rolled into thin sheets known as?

• Ductility

• Malleability

• Conductivity

• Tensile strength

Which property refers to the ability of a material to conduct electricity?

• Ductility

• Malleability

• Conductivity

• Compressive strength

What is the maximum stress a material can withstand when being stretched or pulled before failing or breaking?

• Tensile strength

• Compressive strength

• Durability

• Conductivity

Which of the following best describes compressive strength?

• The ability to withstand squeezing or compression

• The ability to stretch without breaking

• The ability to return to original shape after deformation

• The ability to conduct heat

What does the term "durability" refer to in the context of material properties?

• The ability to conduct electricity

• The ability to withstand environmental conditions without degrading

• The ability to be drawn into wires

• The ability to be compressed without losing shape

How do environmental conditions affect the degradation of materials?

• They have no effect

• They can accelerate degradation through processes like corrosion and weathering

• They can improve the material's properties over time

• They only affect organic materials

What is the significance of a material's chemical composition in determining its properties?

• It has no significance

• It only affects the color of the material

• It determines the material's physical and chemical properties, including strength, ductility, and resistance to corrosion

• It only determines the material's melting point

Failure in materials science is often a result of which of the following?

• Improper use of the material for an unintended purpose

• Exceeding the material's tensile strength

• Both A and B

• Neither A nor B
