Open Scied Transfer of Energy

#1 Energy transformation occurs when a splitting atom releases energy to heat water to produce steam. How do you describe this energy transformation?

• Chemical energy to heat energy
• Electrical energy to heat energy
• heat energy to nuclear energy
• nuclear energy to heat energy

#2 When a hawk eats a mouse and then uses the energy from the mouse to fly, the hawks body converts-

• mechanical energy to chemical energy
• thermal energy to mechanical energy
• chemical energy to mechanical energy
• mechanical energy to thermal energy

#3 two friends decide to go to the park and watch a movie on a computer. the computer runs on battery power. What energy transformation happens from the batter to the light being given off by the computer

• chemical, electrical, light
• chemical, electrical, sound
• electrical, light, sound
• electrical, chemical, light

#4 the diagram shows a hot plate and an electrical outlet.
What energy transformation occurs when the hot plate is plugged into the outlet and the control knob is in the "on" position?
