Item SC100003: Two liquids with the same flammability, boiling point, and color could be the same substance. (This item uses a table that lists properties of the solids.)
Using the information about the five liquids in the table below, which of the following liquids could be the same substance?

- Disciplinary Core Ideas
- PS1.A Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it.
- NRC Framework
- Patterns: …objects can be classified into groups on the basis of similarities of visible or microscopic features or on the basis of similarities of function…
