• 3. Trace the energy transformation of a refrigerator.
• 4. Trace the energy transformation of an electric fan.

ANSWER

• 1.RON CAN MAKE FIRE WITH WOOD TO MAKE IT LIGHT.

• 2.AMY RADIO IS BROKEN BECAUSE SHE NEVER TURN AT OF IT MAY CAUSE FIRE.

• 3.The energy source is electrical power, which would then produce kinetic energy to work the pumps, which would circulate the refrigerant. This reduces the heat in the fridge, increasing the external heat. The wasted energy of the the fridge would be heat and sound.

• 4.The correct option is D Electrical energy - Kinetic energy.When we switch on a fan, the fan converts a significant portion of the electrical energy into kinetic energy of the fan blades. Some part of electric energy is converted into heat. So the correct energy transformation will be:Electrical energy → Kinetic energy
