Conduction, Convection, & Radiation

Front

What are the three 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 and 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, such as infrared radiation, and does not require a medium.

Front

How does convection occur in a boiling pot of water?

Back

In a boiling pot of water, hot water at the bottom expands, becomes less dense, and rises, while cooler water descends, creating a convection current.

Front

What happens to air when it is heated?

Back

When air is heated, it expands, becomes less dense, and rises.

Front

What is the role of density in convection?

Back

Density differences drive convection currents; warmer, less dense fluid rises while cooler, denser fluid sinks.

Front

How does convection affect weather patterns?

Back

Convection plays a significant role in weather patterns by causing air movement, leading to cloud formation and precipitation.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of radiation in everyday life?

Back

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