Conduction, Convection, Radiation

Front

What is the definition of CONDUCTION?

Back

When heat transfers from objects that are touching.

Front

What is CONVECTION?

Back

The transfer of heat through the movement of fluids (liquids or gases) where warm fluid rises and cool fluid sinks.

Front

What is RADIATION?

Back

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

Front

What happens to warm air in a room?

Back

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

Front

What is an example of conduction?

Back

A snowball melting in your hand.

Front

What is an example of convection?

Back

Warm air rising from a heater and cool air sinking.

Front

What is an example of radiation?

Back

Getting sunburned from the sun's rays.

Front

How does heat transfer in a solid?

Back

Through conduction, as particles are in direct contact.

Front

How does heat transfer in liquids and gases?

Back

Through convection, as warmer, less dense areas rise and cooler, denser areas sink.

Front

What is the role of density in convection?

Back

Warm fluids are less dense and rise, while cool fluids are more dense and sink.
