HEAT

HEAT

1. Thermal energy is a form of energy that is transmitted as heat.

   • termperature = heat
     • temperature is the amount of thermal energy
     • Heat is the transfer of thermal energy.

2. How does it travel?

   • CONDUCTION
     • two objects are in contact
     • heat is transferred from one object to another
   • CONVECTION
     • through gases and liquids
     • circular movement
   • RADIATION
     • particles aren't needed
     • transferred through empty space by electromagenetic waves

3. CONDUCTORS AND INSULATORS

   • CONDUCTORS
     • transferred thermal energy easily
   • INSULATORS
     • don't transferred thermal energy easily

4. THE EFFECTS OF HEAT

   • SOLIDIFICATION
     • MELTING
   • CONDENSATION
     • EVAPORATION
   • EXPANSION
     • molecules vibrate
   • CHEMICAL CHANGES
     • when we cook
