Change in Physical State. Heat also affects how molecules interact with each other. Heating a solid above a certain temperature will cause it to melt to form a liquid; further heating causes this liquid to boil to form a vapor.
When water is in its solid state (ice) , the water molecules are packed close together preventing it from changing shape. Ice has a very regular pattern with the molecules rigidly apart from one another connected by the hydrogen bonds that form a crystalline lattice.
What happens when ice melts? What does it turn into and what chemical process does it undergo? It's for a science project, not school or anything, just on my own. I know hydrogen peroxide turns into water if you leave it in the sun, but if you leave an ice cube in the sun it melts down and it's not solid anymore... I'm confused..?
