Conduction

Front

What type of heat transfer occurs when you feel heat from a fire above you?

Back

Radiation

Front

What is the relationship between temperature and kinetic energy of particles?

Back

Higher temperature means higher kinetic energy.

Front

What happens to the kinetic energy of cold things?

Back

Cold things often have lower kinetic energy because particles are moving around less.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves.
