Mi Micro cro 6. The diagram below shows a schematic of eight water molecules (spheres) at 25 ˚C with accent line to represent movement. In the right frame, draw a diagram showing the eight water molecules after the water has heated to 90 ˚C. And in the third frame, show what the molecules will look like while boiling.

Symbolic 7. Why is there a difference between the pictures? That is, what type of change took place? Did this change require energy? If so, what is the source of this energy? Explain using equations....
