(a) Figure P7.21 shows initial and final energy bars for a closed system. Adjust the height of any two energy bars in the final version, on the right, so that the diagram does not violate what we know about energy. (There are numerous ways for you to do this.)

(b) Describe an interaction that would generate an energy bar diagram that matches your version of Figure P7.21.
