Thermal Energy Review

Front

What are the three types of heat transfer?

Back

Radiation, Conduction, Convection

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves, such as light, without needing a medium.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

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

In heat transfer, heat always flows from which substance to which substance?

Back

Heat always flows from hotter substances to colder substances.

Front

What happens to the kinetic energy of particles in cold substances?

Back

Cold substances have lower kinetic energy because their particles are moving around less.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot from being in a pot of hot soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

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

Front

What is an insulator?

Back

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