Conduction, Convection, Radiation Review

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact of molecules or particles with each other.

Front

What is convection?

Back

Convection is the transfer of thermal energy through a fluid (gas or liquid) caused by the movement of the fluid itself.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy in the form of electromagnetic waves, such as light or heat from the sun.

Front

Example of conduction?

Back

An ice cube melting in a person's hand.

Front

Example of convection?

Back

A furnace heating the air in a school.

Front

Example of radiation?

Back

Laying out in the sun at a beach.

Front

Which method of heat transfer does NOT require direct contact?

Back

Radiation.

Front

What happens to air when it is heated?

Back

It becomes less dense and rises, creating convection currents.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, such as rubber or wood.

Front

What is the role of thermal energy in conduction?

Back

Thermal energy is transferred from the hotter object to the cooler object through direct contact.
