Determine the amount by which the stars thermal radiation

Reference no: EM13105912

A given star is a sphere with a radius of 6.11x108 m and an average surface temperature of 6790 K. Determine the amount by which the star's thermal radiation increases the entropy of the universe each second. Assume that the star is a perfect blackbody, and that the average temperature of the rest of the universe is 2.73 K. Do not consider thermal radiation absorbed by the star from the rest of the universe.
