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 the movement of fluids (liquids or gases) where warm areas rise and cool areas sink.

Front

What is Radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

Example of Conduction?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

Example of Convection?

Back

Warm air rising from a heater and cool air sinking.

Front

Example of Radiation?

Back

Feeling the warmth of the sun on your skin.

Front

What happens to warm water in a swimming pool?

Back

Warm water rises due to convection.

Front

What type of heat transfer occurs when you hold a snowball?

Back

Conduction occurs when the heat from your hand melts the snowball.

Front

What is the role of density in Convection?

Back

Warm liquids or gases become less dense and rise, while cool ones become more dense and sink.

Front

How does the sun warm the Earth?

Back

The sun warms the Earth through radiation.
