Phase Diagram

Phase Diagram. Is a graphical representation of the conditions of temperature and pressure at which solids, liquids and gases exist. It may exist either as single phases or states of matter or two or more phases in equilibrium with one another. Phase Diagram for Iodine. Phase Diagrams.

Heating and Cooling Curves

Heating and Cooling Curves. A heating curve is a plot of the temperature of substance versus the heat added to the substance. The graph shows the response of the different phases to added heat (heat capacity) and the heat needed for phase transitions (melting, boiling).
