    Gizmos Name: Hao Lin Date: 4 19/24 StudentExpJpration Phase Changes Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: altitude, boil, boiling point, freeze, freezing point, gas, liquid, melt, melting point, phase, solid Gizmo Warm-up In the Phase Changes Gizmo, select Micro view and set the Ice v o l u m e to 50 cm * 3 4 . Notice the nitrogen (ft ), oxygen (ft ), and water ( P ) molecules. Click Play ( ► ) and observe water molecules in the solid (ice), liquid (water), and gas (air) phases. 1 In wh ich ph ase(s) are th e m oIecuIes held rigidly togeth er? The solid phase is when they are held rigidly together 2. I n w h i c h p h a s e ( s ) d o t h e m o l e c u l e s m o v e freely ? In the gaseous phase, they move freely They are held in a defined shape when a solid Th ey take th e sh a pe of th eir co ntainer wh en it is a liquid or a gas 3. In which phase(s) are the molecules held in a defined shape? 4. In which phase(s) do the molecules take the shape of their container?

    Activity A: Phase changes Get the Gizmo ready: * Click Reset ( } and select Macro view * Set the Water temperature to 10 C C * Set the Ice volume to 0 cm 3 4 5 . 1 i / Question: How is temperature related to phase changes? 1. Investigate: Use the Gizmo to explore phase changes. Use the Add/remove heat energy slider to control the water temperature. The GRAPH tab may be useful too. A. At what temperature does water freeze? OC This is the freezing point. B. At what temperature does ice meIt? o c This is the melting point. C. At what temperature does water bo11? 100 c This is the boiling point 2. Observe: Set up the Gizmo to observe freezing. What do you notice about the temperature while the water is in the process of freezing? Temperature stays the same 3. Explore: Use the Gizmo to investigate melting and boiling. Does the temperature change while either of these phase changes is occurring? The temperature stays the same 4. Interpret: Select the GRAPH tab to see a graph of temperature vs. time. Click the " button until the whole graph is visible. What does the graph look like during a phase change? It's flat after being linear 5. Extend your thinking: Why do you think the temperature does not change much during a phase change? Discuss your answer with your classmates. Because the change from liquid to gas caps the highest temperature it can be at : when it is boiling the water won't get any hotter because at that temperature it stops becoming liquid
