Conduction, Convection, and Radiation Flashcardizz

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through physical touch.

Front

Give an example of conduction.

Back

An example of conduction is an ice cube melting in a person's hand.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink.

Front

Give an example of convection.

Back

An example of convection is warm air rising from a heater and circulating around a room.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves. It does not require a medium (like air or water) to transfer heat.

Front

Give an example of radiation.

Back

An example of radiation is the heat from the sun warming your skin.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat to pass through it easily.

Front

What is the primary way heat travels through liquids and gases?

Back

Convection is the primary way heat travels through liquids and gases.

Front

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, creating a convection current.
