Introduction Which of the following energy sources does not come from solar energy? A Tidal Energy Strictly speaking, except for geothermal energy and nuclear atomic energy, all other energy sources on earth come from solar energy. This is “generalized space energy”.

Which of the following energy sources does not come from solar energy?

Tidal energy

Strictly speaking, with the exception of geothermal energy and atomic nuclear energy, all other energy sources on earth come from solar energy. This is “generalized solar energy” to distinguish it from “generalized solar energy”. “solar energy” which refers only to the energy of solar radiation. The difference between "solar energy" in the narrow sense.

Tidal energy is linked to the moon!

Solar energy is a clean energy source. A solar water heater can increase the temperature of 200 kg of water by 30 ℃ every day, then the heat absorbed by the water is

50 ℃

< td>

Analysis of test questions: Knowing the efficiency of the solar water heater and the solar energy received by the water heater, we can calculate the heat absorbed by the water and cKnow the quality of the water, the specific heat capacity of. water and use the endothermic formula to calculate the final temperature of the water.

The mass of water is m=PV=1.0×10 3 kg/m 3 ×200×10 -3 m 3 =200kg

We know that the reservoir d Water from a solar water heater is heated by the sun. The radiation is 8.4×10 7 J. If 50% of this heat is absorbed by 200 L of water in the box, the heat absorbed by the water is absorption Q. =50%×Q radiation=50 %×8.4×10 7 J=4.2×10 7 J

The temperature that causes the water to rise is

Asia The first MW (megawatt) solar tower thermal power plant is nearing completion in Yanqing County, Beijing (40°N). A 100 meter high solar energy tower will be built by then

2.52×10 7 J? 0.36m 3

< /table>

The declaration following is correct: A. High purity silicon can be used to make solar cells, the working principle of which is different from that of primary cells B. 3O 2 (g)=2O 3 (g)

< p>

Analysis of test questions: Heat absorbed by the water: Q absorption=Cm△t=4,2×10 3 J/(kg﹒℃)×200kg×30℃=2.52×10 7 J; according to the meaning of the question, Q sucks = Q releases, ∵Q releases = qv, ∴ The volume of natural gas required:

Short question 1: C

Short question 2: C

Analysis of the test questions:

Short question 1: According to the principle of the solar heat absorption tower, the angle of the heliostat is related to the altitude angle of the sun, that is, it is as perpendicular to the sunlight as possible. The month when the Beijing solar energy heliostat body. The closest station to the vertical position at noon is the height of the sun at noon in Beijing. The smallest month, the haThe height of the sun at noon in Beijing in December is the smallest among the months offered by the option. The answer is C.

Quiz 2: The altitude angle of the sun at noon is equal to 90 degrees minus the number of latitudes between a certain location (the desired location) and the direct point. The day when the mirror body is closest to vertical should be December 22, when the sun shines directly on the Tropic of Capricorn. By substituting the formula into the calculation, we can get the height of the sun at noon in Beijing = 90°-(40°+.23.5°) = 26.5°.

One

Analysis of test questions: A. High purity silicon is a material for making solar cells that convert solar energy into electrical energy, and primary cells convert chemical energy into electrical energy. . The principles of operation of the two Different, corrects: B and O 2 are converted to O 3 and absorb heat, indicating that the energy of O 3 is greater than O 2. The higher the energy, the more unstable it is, hence oxygen. is more stable than ozone, incorrect; C and S burn with sufficient O 2 , can only generate SO 2 , incorrect. Thunderstorms can produce nitric acid, and nitric acid reacts with ground material to form nitrates, which increases the effectiveness of fertilizers; fake.
