B) How does the thermal energy of solid water change as it melts?

Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!

Hope this helps!! Stay safe! <3

not only is it colder, it also becomes darker, less salty, and more dense.
