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, which can occur in a vacuum.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is an ice cube melting in a person's hand.

Front

Give an example of convection in everyday life.

Back

An example of convection is when you are making soup and the water is rising and lowering.

Front

Give an example of radiation in everyday life.

Back

An example of radiation is the heat from a lamp warming a lizard.

Front

What happens to temperature during conduction?

Back

Heat transfers from an area of high temperature to an area of low temperature.

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

How does radiation differ from conduction and convection?

Back

Radiation does not require a medium to transfer heat, while conduction and convection require matter.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat, as they are at the same temperature.
