So I remember from my fourth grade physics that when you heat something, its atoms and molecules come together, or decrease their intermolecular space. But when you heat something for some time, it turns into a liquid, a form of matter with waaaaay more intermolecular space than a solid let alone a hot solid. So how does that happen?
In: Physics
When you heat something up youre pumping energy into a certain system. The molecules in a solid are normally tightly packed, bound together and vibrating, but when you heat something up enough, the molecules begin to seperate, zooming around rather than just vibrating. This is what melting is: something has gained enough energy to dissolve its structure and flow around
