A. Solar thermal power plants convert solar energy into internal energy. Therefore, A is consistent with the meaning of the question.
B. Photovoltaic panels, the power source for artificial Earth satellites, convert solar energy into electrical energy. Therefore, B does not answer the meaning of the question.
C. Solar cells convert solar energy into electrical energy. Therefore, D does not answer the meaning of the question.
D. CD does not use solar energy, so D does not answer the meaning of the question.
Then choose A
At present, there are two ways for people to use solar energy directly: one is to convert solar energy into internal energy, such as: ______. The second is to convert solar energy into electrical energy
Convert internal energy into light energy such as: flashlight, miner's lamp, i-lampncandescenceetc. Incandescent lamps first convert electrical energy into internal energy, and then convert the internal energy into light energy. Light energy is converted into internal energy, such as a solar water heater which heats water using solar water heaters.
The reason sunlight illuminates the air is that the spaces between air particles can respond to the amplitude of the vibrations of the light waves. When the spaces between molecules are smaller than the amplitude of light wave vibrations. the molecules follow the parameters of the light wave. During vibration, collisions will occur and internal energy will be converted.
Conversion of mechanical energy into chemical energy:
Drilling wood to make fire first converts mechanical energy into internal energy, until combustion releases chemical energy, then theChemical energy is converted into internal energy and light energy. There is a process of converting mechanical energy into chemical energy. Smashing cannons (a kind of firecracker that explodes when released), bullets and cannonballs emit mechanical energy which is converted into internal energy, then the gunpowder explosion releases energy chemical, it can therefore also be considered as an example of mechanical energy conversion. in chemical energy.
Convert light energy into mechanical energy:
For example, during wind formation, sunlight causes different temperatures and pressures of the air, and the air flows towards the form of wind. Wind energy can be considered a type of mechanical energy. Another example is that of the various tools driven by solar cells, which are examples of converting solar energy into electrical energythen in mechanical energy.
Should energy conversion be done through work? How do you explain the conversion of solar energy into internal energy?
At present, there are two ways for people to use solar energy directly: one is to convert solar energy into internal energy, and the other is to convert solar energy. solar energy into electrical energy. Solar water heaters convert solar energy into internal energy and solar cells convert solar energy into electrical energy. Indirect uses of solar energy include: hydroelectricity, fossil fuels, wind energy, etc.
So the answer is: solar water heaters, solar cells, hydropower (or the use of petrochemical power, wind power, etc.).
It has never been said that “the transformation of energy must be achieved through work”. It's initself a false proposition.
For example, you said that solar energy is converted into thermal energy, electrical energy, etc., and the potential energy of objects is converted into kinetic energy. These energy conversions do not require work.
However, the “law of conservation of energy” remains valid whether or not work is done during the energy conversion process.
