11. Chapter: 1 Lesson: 4 Question: A. What is the change in internal energy for each of the following situations? 1.q= 7.9 J out of the system and w = 3.6 J done on the system II. q=1.5 J into the system and w = 7.5 J done on the system B. Assuming both of these systems had the same internal energy initially, which of the two is lower in energy (more stable) after these changes? Hint: AE = q + w See this sample problem if you need help.
