Review: Convection, Conduction, Radiation

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas of a fluid rise and cooler 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

How does heat transfer occur when two objects are touching?

Back

Heat is transferred by conduction when two objects are in direct contact.

Front

What happens to air when a door is opened in winter?

Back

Hot air escapes and cold air enters, demonstrating convection.

Front

What is the primary method of heat transfer in boiling water?

Back

Convection is the primary method of heat transfer that causes a pot of water to boil.

Front

What is an example of conduction in cooking?

Back

A metal pan being heated on the stove is an example of conduction.

Front

Which material is the best conductor of heat?

Back

A metal pan is the best conductor of heat among the options provided.

Front

What is an insulator?

Back

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

Front

What is an example of radiation in everyday life?

Back

The warmth felt from the sun on your skin is an example of radiation.
