To determine the phase of matter shown in the diagrams, the following questions would be most effective:
C. How close are the molecules?
- This question helps to differentiate between solids, liquids, and gases, as solids have closely packed molecules, liquids have molecules that are close but can move past each other, and gases have molecules that are far apart.
E. How quickly do the molecules move?
- This question provides insight into the energy and temperature of the molecules, helping to distinguish between the phases: solids have slower moving molecules, liquids move faster, and gases move even more rapidly.
F. Do the molecules have fixed positions?
- This question is crucial for identifying solids (which have fixed positions), liquids (which do not have fixed positions but are close), and gases (which have no fixed positions).
So the selected questions are C, E, and F.
