Which of the following statements about the rate of stellar evolution is TRUE?
A) The more massive the original star,the faster the evolution.
B) Star mass has no bearing upon stellar evolution because all stars evolve at the same rate,controlled by nuclear fusion and core temperature.
C) The chemical makeup of the original nebula is the major factor in deciding the rate of evolution.
D) The more massive the original star,the slower the evolution because there is more material for thermonuclear burning.

Question

Quizplus · Accepted Answer

The more massive the original star, the faster the evolution. This is because more massive stars have higher temperatures and pressures in their cores, which allow for faster and more efficient nuclear fusion reactions. This leads to a faster consumption of fuel and a shorter overall lifespan.
