Material Properties Quiz

What are the working properties of materials?

• Absorbency, elasticity, magnetism, weight

• Transparency, malleability, reflectivity, hardness

• Weight, texture, color, size

• Strength, flexibility, durability, conductivity, appearance

Differentiate between ferrous and non-ferrous metals.

• Ferrous metals are non-magnetic, while non-ferrous metals are magnetic.

• Ferrous metals contain iron, while non-ferrous metals do not contain iron.

• Ferrous metals contain gold, while non-ferrous metals contain iron.

• Ferrous metals are lightweight, while non-ferrous metals are heavy.

Explain composite materials and provide examples.

• Examples of composite materials include glass and wood

• Composite materials are materials made from two or more different materials with different properties combined to create a new material with enhanced characteristics. Examples include fiberglass, carbon fiber, and concrete.

• Composite materials do not have enhanced characteristics

• Composite materials are made from a single material

Discuss the properties of smart materials.

• Smart materials are not technologically advanced

• Smart materials have the ability to respond to changes in their environment or external stimuli by altering their properties.

• Smart materials are only used in construction

• Smart materials do not change their properties based on external stimuli

How do ferrous metals differ from non-ferrous metals?

• Ferrous metals contain gold, non-ferrous metals contain iron.

• Ferrous metals contain iron, non-ferrous metals do not contain iron.

• Ferrous metals are lightweight, non-ferrous metals are heavy.

• Ferrous metals are non-magnetic, non-ferrous metals are magnetic.

Give an example of a composite material and its properties.

• Aluminum - Low weight, high corrosion

• Steel - Low strength, high flexibility

• Carbon fiber - Low strength-to-weight ratio, high rigidity

• Fiberglass - High strength-to-weight ratio, corrosion resistance, flexibility

What makes a material 'smart'?

• Ability to sense and respond to internal stimuli

• Ability to sense and respond to external stimuli

• Ability to sense and respond to thoughts

• Ability to sense and respond to emotions

Name one ferrous metal and one non-ferrous metal.

• Lead

• Copper

• Iron

• Steel, Aluminum

How can smart materials change their properties?

• Smart materials change their properties by doing a dance

• Smart materials change their properties by reading a book

• Smart materials change their properties by responding to external stimuli such as temperature, light, pressure, or magnetic fields.

• Smart materials change their properties by singing a song

Why are composite materials used in various industries?

• Composite materials offer a combination of desirable properties such as high strength-to-weight ratio, corrosion resistance, and design flexibility.

• Composite materials are not used in any industries

• Composite materials are only used for aesthetic purposes

• Composite materials are cheaper than traditional materials
