Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy by collisions between particles.

Front

What is convection?

Back

Convection is the transfer of thermal energy in a fluid (liquid/gas) by movement of warm/cool fluids.

Front

What is radiation?

Back

Radiation is the transfer of heat through waves, such as heat from the sun.

Front

Example of conduction in everyday life?

Back

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

Front

Example of convection in everyday life?

Back

Boiling water where hot water rises and cool water sinks.

Front

Example of radiation in everyday life?

Back

Feeling warmth from a campfire or heat lamp.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter.

Front

How does conduction occur?

Back

Conduction occurs when two objects at different temperatures are in direct contact.

Front

How does convection occur?

Back

Convection occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

How does radiation differ from conduction and convection?

Back

Radiation does not require a medium; it can occur in a vacuum.
