Conduction Convection Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, which can occur in a vacuum.

Front

What is a good conductor of heat?

Back

A good conductor of heat is a material that allows heat to pass through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing heat transfer, such as plastic, rubber, or wood.

Front

How does heat transfer in conduction?

Back

In conduction, heat is transferred when particles in a hotter object collide with particles in a cooler object, transferring energy.

Front

How does heat transfer in convection?

Back

In convection, heat is transferred by the movement of fluid, where warmer fluid rises and cooler fluid sinks, creating a circulation pattern.

Front

How does heat transfer in radiation?

Back

In radiation, heat is transferred through electromagnetic waves, allowing energy to travel through space without needing a medium.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection?

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks.
