Question
Chapter 13, Problem 1QAP
To determine
The given statement is true or false.
Expert Solution & Answer
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.
Conclusion:
Thus, the given statement is true.

Multiple Choice
During the intermediate step of solar nuclear fusion
a. 1 deuterium fuse with 1 proton making helium-3
b. 2 protons fuse together making helium-3
c. 2 deuterium nuclei fuse together making helium-3
d. 1 deuterium fuse with 1 proton making helium-4
Both the CNO cycle and the proton–proton chain combine 4 H nuclei to produce 1 He nucleus. Would those two processes release the same amount of energy per He nucleus produced?
Calculate the total energy output per second in watts (W) of a star that converts 900 million tonnes of hydrogen per second into helium, with a mass difference of 6.30 million tonnes per second due to nuclear fusion. Use E = Δmc2 and c = 3.0 × 108 m s-1.
