Which of the Following Best Explains Why the Sun's Luminosity

question 25

Multiple Choice

Which of the following best explains why the Sun's luminosity gradually rises over billions of years?

• A)Fusion gradually decreases the number of independent particles in the core,allowing gravity to compress and heat the core,which in turn increases the fusion rate and the Sun's luminosity.
• B)Nuclear reactions in the Sun become more efficient with time,so that each fusion reaction releases more energy when the Sun is old than when it is young;this in turn raises the Sun's luminosity.
• C)The Sun's core gradually expands with time,and this expansion means there is more room for energy to be generated and hence increases the Sun's luminosity.
• D)The planets need more and more energy to maintain any life on them as time goes on,and therefore the Sun must bet hotter.
