CI6: Conductors and Insulators

Front

What is a conductor?

Back

A material that allows heat or electricity to flow through it easily.

Front

What is an insulator?

Back

An object that transfers heat poorly.

Back

Wool.

Front

What is the role of a vacuum in a thermos?

Back

It reduces energy transfer by preventing heat conduction and convection.

Front

What is thermal conductivity?

Back

The ability of a material to conduct heat.

Front

What is the difference between conductors and insulators?

Back

Conductors allow heat/electricity to flow; insulators resist heat/electricity flow.
