Question

Using the interactive diagram, you can observe what the phase of CO2 is at a particular temperature and pressure by moving the cursor to that point on the phase diagram. The animation also shows the type of movement experienced by CO2 molecules in a particular phase. You are given six samples of carbon dioxide (CO2) that are stored at different temperatures and at different pressures. Using the interactive activity showing the phase diagram of CO2, determine the phases of each of the samples and classify them according to which phase they are in. Keep in mind that the temperature and pressure are not to scale. Drag the appropriate items to their respective bins.
