Question 10 Tries remaining Points out of 100 Flaggston What is the overall change in entropy (J/K) of the 'universe' for the condensation of an unknown substance B? The change in entropy for the process is -8.8 J/K and the change in entropy for the surroundings is 12.2 J/K. Multiple tries are permitted; however, 20% (1/5) point will be deducted for each incorrect response Answer: Check
