Thermal Energy - Heat Transfer

Front

Thermal Energy

Back

the energy of particles in motion which can be described as heat

Front

What are the three ways that heat is transferred in thermal energy?

Back

Conduction, convection, and radiation

Front

Heat transfer by convection happens when:

Back

there is a circulation of hot air/water rising and cold air/water sinking

Front

Heat transfer by radiation happens when:

Back

there is space that heat travels though in waves outwardly

Front

Heat transfer by conduction happens when:

Back

two objects are touching and heat moves from one object into the next object

Front

Wool, feathers, cotton, Styrofoam are all examples of good:

Back

insulators of thermal energy

Front

All metals are examples of good:

Back

conductors of thermal energy

Front

A hot air balloon rising and falling as the balloon's air is heated or cooled is an example of which type of energy transfer?

Back

convection

Front

Holding a hot cup of cocoa is an example of which type of heat transfer?

Back

conduction

Front

Thermal energy traveling though space from the sun toward earth in waves is an example of which type of heat transfer?

Back

radiation
