Physical Properties Missed Out …

Question 1

What is a material that is an electrical conductor?

Answer 1

Allows the flow of electrical current through the material. Has little resistance to the flow of charge

Question 2

What is a material that is an electrical insulator

Answer 2

Does not allow the flow of electricity through the material

Question 3

What is a material that is an thermal conductor

Answer 3

Allows the transfer of heat energy through the material. A material with high conductivity will allow the tranfer of heat to occur quickly across the material

Question 4

What is a material that is an thermal insulator

Answer 4

Prevents the transfer of heat through the material

Question 5

What is a material that is a thermal expansion?

Answer 5

The increase in material volume in response to the heat input

Question 6

What is a material that is opaque

Answer 6

Regents light from travelling through

Question 7

What is a material that is translucent

Answer 7

Allows light through but diffuses the light so that objects appear blunt. E.g frosted glass

Question 8

What is a material that is transparent

Answer 8

Allows light to pass through easily which means you can see clearly through the material
