Convection, Conduction, Radiation

Front

What is Convection?

Back

Convection is the transfer of heat through a fluid (liquid or gas) where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is Conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

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 in Convection?

Back

In convection, heat is transferred by the movement of fluids. Warmer fluid rises while cooler fluid sinks, creating a circulation pattern.

Front

What happens to molecules when they are heated?

Back

When molecules are heated, they move faster and spread apart, causing the substance to expand.

Front

What is an example of Conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot pot of soup.

Front

What is an example of Convection?

Back

An example of convection is warm air rising and cool air sinking in a room heated by a radiator.

Front

What is an example of Radiation?

Back

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

Front

What happens to an egg placed on hot pavement?

Back

The pavement will conduct heat and cook the egg.

Front

What is the relationship between molecular movement and temperature?

Back

The quicker a molecule moves, the warmer it is.
