Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat from one object to another through direct contact.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation.

Front

What is needed for convection to occur?

Back

Fluids (liquids or gases) are needed for convection to happen.

Front

How does heat transfer occur between areas of different temperatures?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

What is the best surface for reflecting heat radiation?

Back

A shiny white surface is the best for reflecting heat radiation.

Front

Give an example of conduction in everyday life.

Back

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

Front

Give an example of convection in everyday life.

Back

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

Front

Give an example of radiation in everyday life.

Back

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

Front

What happens to a fluid when it is heated?

Back

When a fluid is heated, it expands, becomes less dense, and rises.
