This is what they wrote: "A heating curve shows how the temperature of a molecule changes as it is heated. First, it starts as a solid below its melting point. Then, as heat is put in, the bonds start to break at the phase change, and the molecule becomes a liquid. The temperature of the molecule cools slightly at this point. Then, the temperature rises again because the heat going in makes the molecules have greater potential energy (motion). At its boiling point, more bonds break and it turns into a gas. The phase changes are the flat regions of the heating curves because all the heat going in is used to break the bonds." While they have a lot right, there are a number of mistakes. Highlight or copy-and-paste 2 errors, and explain what is wrong/how to fix the errors.
