Chapter 8, Problem 21SEQ

Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.

*21. The Lifetime of the sun. The Sun’s Mass is about 2 Ă— 1030 kg. ; This mass was about 70% hydrogen when the sun formed, with about 13% of this hydrogen available for eventual in the core.

a. Use the given data to calculate the total mass of hydrogen available for fusion over the lifetime of the Sun.

b. The Sun fuses about 600 billion kilograms of hydrogen each second. Based on your result from part a, calculate how long the Sun’s initial supply of hydrogen can last. Give your answer in both seconds and years.

c. Given that our solar system is now about 4.6 billion years old, when will the Sun run out of hydrogen for fusion?
