Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight, which can travel through a vacuum.

Front

In which process does heat transfer occur from a hot object to a cold object?

Back

Heat always flows from the hotter substance to the colder substance.

Front

What happens to warm air in convection?

Back

Warm air rises because it is less dense than cooler air.

Front

What is an example of conduction?

Back

Ironing a shirt is an example of conduction, where heat is transferred from the iron to the fabric.

Front

What is an example of convection?

Back

Boiling water is an example of convection, where hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

The warmth felt from sunlight is an example of radiation.

Front

How does conduction occur in metals?

Back

In metals, conduction occurs as free electrons move and transfer energy from hot regions to cooler regions.

Front

What is the role of the Law of Conservation of Energy in heat transfer?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transferred or transformed.
