What are smart materials?

• Materials that can change their properties in response to external stimuli

• Materials that are always rigid and inflexible

• Materials that are only used in construction

• Materials that are not affected by temperature changes

What is the purpose of piezoelectric materials?

• To generate heat when exposed to moisture

• To change color in response to light

• To resist any form of stress

• To produce a voltage when stress is applied

What is the function of shape memory alloys (SMA)?

• To induce and recover large deformations through temperature changes or stress changes

• To conduct electricity efficiently

• To repel water and moisture

• To produce sound when an electric current is passed through

What is the purpose of temperature-responsive polymers?

• To resist any form of stress

• To undergo changes upon temperature

• To change color in response to light

• To produce a voltage when stress is applied

What do chromogenic systems do?

• Induce and recover large deformations through temperature changes or stress changes

• Produce sound when an electric current is passed through

• Produce a voltage when stress is applied

• Change color in response to electrical, optical, or thermal changes

What is the purpose of EZ Track paint?

• To go on pink and dry bright white for easy application

• To create a distinct contrasting light pink color

• To change color in response to light

• To produce sound when an electric current is passed through

What is the function of polymorph?

• To change color in response to light

• To produce a voltage when stress is applied

• To become flexible and easy to shape when heated in boiling water

• To resist any form of stress

What is a composite material?

• A material that is only used in construction

• A material that is always rigid and inflexible

• A material that can change its properties in response to external stimuli

• A mixture composed of two or more substances with one substance acting as the matrix or glue

What is nanotechnology?

• The creation of materials that can conduct electricity efficiently

• The study of controlling matter on an atomic and molecular scale

• The production of materials that resist any form of stress

• The process of changing color in response to light

What is the purpose of the Health and Safety at Work Act 1974?

• To prevent the unlawful acquisition, possession, and use of dangerous substances

• To protect persons against risks to health or safety arising out of activities at work

• To secure the health, safety, and welfare of persons at work

• To control the keeping and use of explosive or highly flammable substances
