Thermal/Heat Transfer

Thermal Energy is

• the energy of electrons moving through a circuit

• the energy stored due to its position

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

• the energy of moving downhill

Three ways that heat is transferred in thermal energy are:

• conduction, convection, and radiation

• temperature, heat, density

Heat transfer by convection happens when:

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

• there is space that heat travels through in waves outwardly

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

Heat transfer by radiation happens when:

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

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

• there is space that heat travels though in waves outwardly

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

• insulators of thermal energy

• conductors of thermal energy

All metals are examples of good:

• insulators of thermal energy

• conductors of thermal energy

What are waves that can transfer heat through the vacuum of empty space?

• Electromagnetic waves
• Convection
• Conduction
• Heat

What is the measurement of the average kinetic energy of a substance?

• Kinetic energy
• Temperature
• Thermal energy
• Potential energy

What happens to particles as they heat up?

• They slow down
• Nothing
• They don't move
• They speed up

As you touch a hot stove the heat transfers -

• from your hand to the stove
• from the stove to your hand
• It doesn't transfer
