What is ductility in terms of materials?

Back

Ductility is the ability of a material to be stretched into a wire without breaking.

Front

What is the difference between metals and nonmetals in terms of conductivity?

Back

Metals are generally good conductors of heat and electricity, while nonmetals are poor conductors.

Front

What is an example of a brittle material?

Back

Glass is an example of a brittle material that shatters when struck.

Front

How does temperature affect the conductivity of metals?

Back

As temperature increases, the conductivity of metals typically decreases due to increased atomic vibrations.

Front

What is thermal conductivity?

Back

Thermal conductivity is the ability of a material to conduct heat.
