Chapter 20, Problem 50P(choose chapter or problem)
Entropy Change Due to the Sun. Our sun radiates from a surface at 5800 K (with an emissivity of 1) into the near-vacuum of space, which is at a temperature of 3 K.
(a) By how much does our sun change the entropy of the universe every second? (Consult Appendix F.)
(b) Is the process reversible or irreversible? Is your answer to part (a) consistent with this conclusion? Explain.
