Conduction, Convection & Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials, occurring in solids, liquids, and gases.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

How does thermal energy move?

Back

Thermal energy moves in a predictable pattern, from warmer sites to cooler sites.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy can neither be created nor destroyed, it just changes form.

Front

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

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

Front

What happens to particles during conduction?

Back

During conduction, particles vibrate and transfer energy to neighboring particles through direct contact.

Front

What happens to particles during convection?

Back

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