A. Green plants convert solar energy into chemical energy through photosynthesis

B. Solar water heaters convert solar energy into the internal energy of water through work.

C. Solar traffic lights convert solar energy directly into light energy of the lights

D. Solar aircraft convert solar energy directly into the mechanical energy of the aircraft

Common mistake point 4: Not knowing the form and transformation of energy

10. There are many forms of energy. The following examples belong to mechanical energy: ①⑤, internal energy: ②③, chemical energy: ⑥, and nuclear energy: ④ (please fill in the serial numbers).

①The energy of flowing water and water at high places; ②The energy of hot water; ③The energy of high-temperature water vapor; ④The energy released by atomic bomb explosions; ⑤The energy of air during the flow process; ⑥The energy of coal

11. Which of the following analysis of energy conversion is wrong (D)

A. Hydropower stations mainly convert mechanical energy into electrical energy

B. Nuclear power plants mainly convert nuclear energy into electrical energy

C. Solar water heaters mainly convert solar energy into internal energy

D. Heat engines mainly convert mechanical energy into internal energy

12. The power plant of a certain hybrid car consists of a gasoline engine and an electric motor. Under normal circumstances, the battery supplies power to the electric motor, which provides power; when larger power is needed, the gasoline engine and the electric motor provide power together; when the car brakes and slows down, the electric motor can also serve as a generator to charge the battery. Regarding the energy conversion of the vehicle's power unit during operation, the following analysis is incorrect (D)

A. The power stroke of a gasoline engine converts internal energy into mechanical energy

B. The electric motor converts electrical energy into mechanical energy when providing power.

C. The engine charges the battery and converts electrical energy into chemical energy

D. The process of braking, decelerating and generating electricity converts internal energy into electrical energy.
