Lesson 6 Quiz 4 / 4 points Most people don't realize that once something starts to melt, cranking up the heat does't make the temperature of the substance higher, at least not until it is ALL melted. When you add lots of extra heat to a solid that is in the process of melting, what ends up happening to all of this extra energy you are adding? It is used to do what? Question options: expand the solid. change solid to liquid. change the liquid back to solid. overcome the intermolecular forces that hold the solid together. raise the temperature of the solid above its melting point.
