First, fold your paper in half like this. Not this. © Carey Munoz

You need four “flaps.” To cut “flaps,” cut only the top half of the folded paper. 1 2 3 4 Do not write these numbers on your flaps! © Carey Munoz

There are four flaps of information. What is the Triple Point? What is the Critical Point? What is the normal boiling point and normal freezing point? What are the possible phase changes? Phase Diagrams – What are they? © Carey Munoz

Under flap 1 – Phase Diagrams – What are they? 2 3 4 Pressure Phase Diagrams are diagrams that describes the state of matter for a substance at any given temperature and pressure. Solid Liquid Gas Temperature © Carey Munoz

Under flap 2 – What are the possible phase changes? 1 2 3 4 Melting Freezing Pressure Boiling Condensation Solid Liquid Sublimation Deposition Gas Temperature © Carey Munoz

Under flap 3 – Triple Point & Critical Point 1 2 3 4 Critical Point Pressure Triple Point – The temperature and pressure where all three states of matter exist at one time Critical Point – The temperature at which only the gas phase exists regardless of pressure Solid Liquid Triple Point Gas Temperature Critical Point © Carey Munoz

Under flap 4 – Normal Boiling and Freezing Points 1 2 3 4 Standard Pressure 1 atm Pressure Normal Boiling Pt – The boiling temp. that occurs at standard pressure Normal Melting Pt – The melting temp. that occurs at standard pressure Solid Liquid Gas Normal Melting Temp. Normal Boiling Temp. © Carey Munoz
