Conduction, Convection, & 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, such as light or infrared radiation, and does not require a medium.

Front

Example of conduction in everyday life?

Back

When a metal spoon is placed in hot soup, the heat from the soup transfers to the spoon, making it hot.

Front

Example of convection in everyday life?

Back

When boiling water, the hot water rises to the top while cooler water sinks, creating a circular motion.

Front

Example of radiation in everyday life?

Back

Feeling warmth from the sun on your skin is an example of heat transfer by radiation.

Front

What happens to heat when ice melts in water?

Back

Heat flows from the warmer water to the colder ice, causing the ice to melt.

Front

How does a lizard stay warm under a lamp?

Back

The heat from the lamp warms the lizard through radiation.

What is the primary method of heat transfer in liquids?

Back

Convection is the primary method of heat transfer in liquids.

What is the primary method of heat transfer in solids?

Back

Conduction is the primary method of heat transfer in solids.
