Question

question 17 of 20 answer bank the sun generates energy by the fusion of hydrogen atoms into helium atoms. sunlight is a consequence of fission reactions the suns core temperature is greater than 10 million k. nuclear reactions take place on the suns surface where the temperature is 580 k the density of the suns core is less than the density of air. the sun is more massive than the earth.

Explanation:

1. The Sun generates energy through the fusion of hydrogen atoms into helium atoms, which is correct.
2. Sunlight is a result of fusion reactions, not fission reactions, so "Sunlight is a consequence of fission reactions" is false.
3. The Sun's core temperature is indeed greater than 10 million K, which is true.
4. Nuclear reactions occur in the Sun's core, not on its surface (where the temperature is much lower than the core, not 580 K for nuclear - reaction conditions), so "Nuclear reactions take place on the Sun's surface where the temperature is 580 K" is false.
5. The density of the Sun's core is much greater than the density of air, so "The density of the Sun's core is less than the density of air" is false.
6. The Sun is much more massive than the Earth, which is true.

Answer:

True: The Sun generates energy by the fusion of hydrogen atoms into helium atoms; The Sun's core temperature is greater than 10 million K; The Sun is more massive than the Earth.
False: Sunlight is a consequence of fission reactions; Nuclear reactions take place on the Sun's surface where the temperature is 580 K; The density of the Sun's core is less than the density of air.
