Estimate the total change in entropy of the universe. Assume all objects are at room temperature (293 KK).
Express your answer to two significant figures and include the appropriate units.
1 Expert Answer
If the question is right, we can find the total energy lost (-76.95 J) divide by the room temperature 293 K. So the change of entropy will be: -0.26 J/K
