The diagram shows a solar-powered air conditioner. The solar cells convert sunlight into electrical energy, which is then used to power the compressor and cool the air. The energy transformations that occur in the diagram are electrical ---> sound ---> light and mechanical.
The correct answer is (A) electrical ---> sound ---> light and mechanical.
The diagram shows a solar-powered air conditioner. The solar cells convert sunlight into electrical energy. The electrical energy is then used to power the compressor, which compresses the refrigerant. The compressed refrigerant is then condensed, releasing heat. The condensed refrigerant then flows through the expansion valve, where it evaporates, absorbing heat from the air. The evaporated refrigerant then circulates through the evaporator coil, cooling the air.
The energy transformations that occur in the diagram are as follows:
Solar energy is converted into electrical energy by the solar cells.
Electrical energy is converted into mechanical energy by the compressor.
Mechanical energy is converted into heat energy by the condenser.
Heat energy is removed from the air and transferred to the refrigerant by the evaporator coil.
Sound energy is produced by the fan.
Therefore, the correct answer is (A) electrical ---> sound ---> light and mechanical.
