Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself. It occurs when two objects at different temperatures are in direct contact.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm fluid rises while cool fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium and can occur in a vacuum.

Front

How does heat transfer occur in a house?

Back

Heat transfer in a house occurs through conduction (in walls), convection (in air circulation), and radiation (from sunlight).

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 warm air rising from a heater and circulating throughout a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What happens to heat during conduction?

Back

During conduction, heat flows from the hotter substance to the colder substance.

Front

What happens to heat during convection?

Back

During convection, heat is transferred by the movement of fluid, causing warmer areas to rise and cooler areas to sink.

Front

What happens to heat during radiation?

Back

During radiation, heat is emitted in the form of electromagnetic waves and can travel through empty space.
