Suppose That,for Some Unknown Reason,the Core of the Sun Suddenly

question 19

Multiple Choice

Suppose that,for some unknown reason,the core of the Sun suddenly became hotter.Which of the following best describes what would happen?

• A)Higher temperature would cause the rate of nuclear fusion to rise,which would increase the internal pressure,causing the core to expand and turn the Sun into a giant star.
• B)Higher temperature would cause the rate of nuclear fusion to rise,which would increase the internal pressure,causing the core to expand and cool until the fusion rate returned to normal.
• C)Higher temperature would cause the rate of fusion to fall,decreasing the internal pressure and causing the core to collapse until the rate of fusion returned to normal.
• D)The higher temperature would not affect the fusion rate but would cause the core to expand and cool until the temperature returned to normal,with the core at a new,slightly larger size.
