7.8A Investigate, Conduction, Radiation

Front

What is conduction?

Back

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

Front

What happens to molecules when they are heated?

Back

The quicker a molecule moves, the warmer it is.

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

How does heat transfer through a metal rod placed in a flame?

Back

Heat is transferred through the rod by conduction.

Front

What is an example of convection in everyday life?

Back

Warmth from a fireplace circulating through a house.

Front

What is an example of radiation?

Back

The warmth felt from the sun on your skin.

Front

What is the role of density in convection?

Back

In convection, hot liquids or gases expand, become less dense, and rise, while cooler, denser liquids or gases sink.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is an example of conduction?

Back

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