  • Hello! I'm going to tell you about this candy bar.
  • See this candy bar? Its a solid right? witch means that the molecules have low energy and and has a strong attraction. But as time goes by, the temperature will stay the same, but the candy bar won't.
  • About an hour has gone by and, like I said, the temperature has stayed at room temperature, but the candy bar is now different. It has gone through a "Phase Change" or changed its form.
  • The candy bar is now a liquid form. A liquid form is when the molecules move around each other, their energy level is medium and the attraction is strong, but also week. it is right in the middle.
  • The candy bar has gone through a phase change called melting. There are different types of phase changes such as freezing and evaporating, but that isn't till next time!
  • Catch ya next time!
