Conduction, Convection, Radiation

Front

What are the three main modes of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

Which surface is best for absorbing heat radiation?

Back

Dull black surfaces are the best for absorbing heat radiation.

Front

What type of heat transfer occurs when you touch a hot stove?

Back

Conduction occurs when you touch a hot stove.

Front

How does a heat lamp warm baby chickens?

Back

A heat lamp warms baby chickens through radiation.

Front

What type of heat transfer is involved when the sun heats your body?

Back

Radiation is involved when the sun heats your body.

Front

What is the role of density in convection?

Back

In convection, warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern.

Front

Can heat transfer occur in a vacuum?

Back

Yes, heat transfer can occur in a vacuum through radiation.
