The ____ is the nuclear fusion of three helium nuclei to form a carbon nucleus.
A) proton-proton chain
B) Carbon-Nitrogen-Oxygen cycle (CNO cycle)
C) triple-alpha process
D) Coulomb barrier
E) infrared cirrus

Question

Quizplus · Accepted Answer

The triple-alpha process is the nuclear fusion of three helium nuclei to form a carbon nucleus. The other options do not describe this process. The triple-alpha process is the nuclear fusion process where three helium nuclei combine to form a carbon nucleus. This process occurs in the cores of red giant stars. The proton-proton chain and CNO cycle are other nuclear fusion processes that occur in stars, but they do not involve the fusion of helium nuclei. The Coulomb barrier and infrared cirrus are not related to nuclear fusion.
