Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another due to a temperature difference.

Front

What is an insulator?

Back

A material that does not conduct heat well, preventing heat transfer.

Front

Give an example of a good insulator.

Back

Wool, plastic, and glass are good insulators.

Front

Which material is NOT an insulator?

Back

Iron is NOT an insulator; it is a conductor.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What is temperature?

Back

A measure of the average kinetic energy of the particles in a sample of matter.

Front

What happens to particles when heat is added?

Back

They speed up and move more vigorously.

Front

What is the direction of heat transfer?

Back

Heat transfers from an area of high temperature to an area of low temperature.
