Energy is transferred in several ways during the solar cooking process. How does heat energy flow in the solar cooker to the pot then water? CHOOSE TWO

• Energy flows from the air outside the solar cooker to the air inside the solar cooker.

• Energy flows from the air inside the solar cooker through the sides of the cook pot and to the water.

• Energy flows from the water through the sides of the cook pot and to the air inside the solar cooker

• Energy flows from the air inside the solar cooker through the sides of the solar cooker and to the air outside the solar cooker.

• Energy flows from the air outside the solar cooker through the sides of the solar cooker and to the air inside the solar cooker.

How does heat transfer?

• Heat does not transfer - all particles remain the same temperature

• Slow (cool) atoms collide with the fast (hot) atoms transferring some of their kinetic energy in the process

• Fast (hot) atoms collide with slow (cool) atoms transferring some of their kinetic energy in the process

What effect does the reflector (foil) on the solar oven have on the transfer of heat?

• If adjusted correctly as the Sun moves throughout the day, the reflector could reflect the direct angle of sunlight into the cooker could allow the water to boil faster.

• If adjusted correctly as the Sun moves throughout the day, the reflector could reflect the direct angle of sunlight into the cooker could allow the water to boil slower.

• The reflector (foil) absorbs the heat and does not transfer heat to the water.

• The reflector (foil) transmits the heat through the pot to the water to allow the water to boil faster.

What would happen if their was no reflector material (foil) on the solar cooker lid?

• Removing the reflector material from the lid will increase the amount of sunlight getting into the solar cooker.

• Removing the reflector material from the lid will have not effect on the amount of sunlight getting into the solar cooker.

• Removing the reflector material from the lid will decrease the amount of sunlight getting into the solar cooker

What term describes this definition: Energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another

• Conservation of matter

• Conservation of energy

• Conservation of sound

• Conservation of chemicals

How can more sunlight be transmitted through the clear part of the solar cooker?

• allow the sunlight to strike the surface more directly

• allow the sunlight to strike the surface more indirectly

• place white paper on the other side of the clear part to absorb more energy
