Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.

Front

Give an example of conduction.

Back

A hot mug of cocoa warming the table it sits on.

Front

What is convection?

Back

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

Front

Give an example of convection.

Back

Boiling water where hot water rises and cooler water sinks.

Front

What is radiation?

Back

The transfer of thermal energy through electromagnetic waves, without needing a medium.

Front

Give an example of radiation.

Back

The sun warming your skin.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is an insulator?

Back

A material that does not conduct heat well, slowing down thermal energy transfer.

Front

Give an example of an insulator.

Back

Wood, rubber, and plastic are good insulators.
