Front

What are the three main types of heat transfer?

Back

Conduction, convection, and radiation.

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

How does heat affect the expansion of materials?

Back

Most materials expand when heated due to increased molecular movement.

Front

What is a good conductor of heat?

Back

A material that allows heat to pass through it easily, like metals.

Front

What is a poor conductor of heat?

Back

A material that does not allow heat to pass through it easily, like wood or plastic.

Front
