slide1

Thermal Energy

Is the total random kinetic energy of particles in an object

Which has more thermal energy? Why?

  • Glass of water
  • Lake Acworth
slide2

HEAT

  • Is a flow of energy from an object at a higher temperature to an object at a lower temperature
  • Heat is the result of molecules vibrating quickly.
  • Heat is moving energy.
  • What happens when you add heat energy to a pot of water?
slide3

Conduction

  • The transfer of heat by direct contact between objects or particles.
slide4

Radiation

  • Heat transferred through space.
  • EXAMPLE: The sun’s rays causing a sunburn.
slide5

Convection

  • Heat transferred by the movement of molecules within a substance (liquids or gases).
  • Movement occurs from warmer areas to cooler areas.
slide6

Convection Current

  • The movement of a substance that is caused by differences in temperature and density.
  • EXAMPLES: wind boiling water
  • NATURE WANTS

EVERYTHING TO BALANCE ! !

slide7

Conductors

  • Conductors are materials that transfer heat easily.
  • Examples: metals like copper and gold
slide8

Insulators

  • An insulator is a material that does not transfer heat easily.
  • Examples:
  • liquids and gases
  • A jacket
