1. Heating and Cooling, the art of Thermal Energy

2. Thermal Energy
Heat flows from warmer objects to cooler objects, until both objects reach the same temperature.
Three ways that heat is transferred:
Convection, Conduction and Radiation.

3. Conduction
The transfer of heat from a warmer to cooler substance through direct contact.

4. Radiation
The transfer of energy as electromagnetic waves. Radiation can occur through empty space.

5. Convection The transfer of heat in a liquid or gas through currents.
Where have we seen this word before?
Electric Current movement of electrons.
Current = Movement

6. Convection
