Question

Heavier elements require higher temperatures to fuse. After stars run out of hydrogen in their cores, they leave the main sequence, collapse, and eventually get hot enough to fuse the helium in their cores into carbon. As discussed in the previous chapter, the Sun will never get hot enough to fuse carbon.Which of these hypothetical situations would allow the temperature of the Sun's core to rise enough for carbon fusion to be possible?Choose one:A. Add mass to the Sun.B. Increase the radius of the Sun.C. Convert all of the Sun's hydrogen into carbon.D. Decrease the radius of the Sun.

Answer 1

Answer:

A. Add mass to the Sun.

Explanation:

A. Add mass to the Sun.

Adding mass will make to take more time for the hydrogen to run out and hence, enough temperature will be developed to fuse helium atom into other heavier elements, and eventually get hot enough to fuse the helium in their cores into carbon.

The only hypothetical solution is that we need to add Mass to the Sun.
