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

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

A thermal insulator:

• does not allow heat to easily pass through it or escape.

• does allow heat to easily pass through it and escape.

Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, denser fluids

• convection

• conduction

• radiation

• temperature
