2. Solar Panels Convert Electromagnetic Energy into Electricity.

4. Some systems use sunlight to heat up oil in tubes which then is used to boil water to produce steam for turning a turbine which then in turn spins a generator.

5.  energy, solar energy, solar oven, heat transfer, conduction, convection, radiation, thermal conductivity, insulator, watt, emissivity, isolation, renewable resource, nonrenewable resource

6.  Explain the three types of heat transfer: conduction, convection and radiation.  Identify materials that are good insulators or conductors of heat.

7.  Conduction = Heat flow due to the direct contact of two objects or within a solid object  Convection = Heat flow due to fluid movement such as the movement of air or water  Radiation = Energy transferred through the movement of electromagnetic waves; heat transfer not requiring a medium

8.  Thermal Conductivity = The property of a material that determines how well it conducts/transmits heat  Insulator/Insulation: A material that does not conduct heat very well and has a low thermal conductivity  Watt (W): The metric (SI) unit for power. (1 horsepower (hp) = 746 Watts (W))

9.  Emissivity: Property of the surface of an object that determines how much electromagnetic energy is reflected and how much is absorbed by an object in the form of heat. Emissivity is very dependent on color.  Insolation/Solar Radiation: The amount of power received on the earth's surface per unit area

10.  Renewable Resource: A resource that is inexhaustible or replaceable by new growth; limitless supply  Nonrenewable Resource: A resource that is not replaceable after it has been used

12. CONDUCTION

15. CONVECTION

23. RADIATION

36. ENERGY VS POWER  Power = Work / time  Power = voltage x current  Energy is the ability to do work.  The faster you use electricity or the faster you do work the more powerful.

37.  How fast heat conducts through a material.
