Heating Curves and Phase Diagrams

How do little scientists know when a liquid will turn into a gas? Scholars explore how heating curves and phase diagrams provide useful information about the states of matter. They learn about the role of kinetic and potential energy in phase changes and  also differentiate between heat of fusion and heat of vaporization.
