Chapter 13, Problem 1QAP

To determine

The given statement is true or false.

Answer to Problem 1QAP

True.

Explanation of Solution

The center of a high mass star is at a very high temperature and several nuclear reactions occurs inside the star. In some of the high mass star, hydrogen is fused into helium following carbon-nitrogen-oxygen cycle.

The CNO cycle uses four hydrogen and convert it into helium. The following reaction takes place during the process.

    ${}^{\text{12}}\text{C}+{\text{4}}^{\text{1}}\text{H}+{\text{2e}}^{-}{\to }^{\text{12}}\text{C}{+}^{\text{4}}\text{He}+\text{2ν}+\text{7γ}$

Conclusion:

Thus, the given statement is true.
