Answer:
The entropy change of the Universe that occurs is 19.346 J/K
Explanation:
Given;
temperature of the sun, = 5,300 K
temperature of the Earth, = 293 K
radiation energy transferred by the sun to the earth, E = 6000 J
The sun loses Q of heat and therefore decreases its entropy by the amount
The earth gains Q of heat and therefore increases its entropy by the amount
The total entropy change is:
Therefore, the entropy change of the Universe that occurs is 19.346 J/K
