A student makes some observations about three solids and summarizes the results in the table above. Could any of the solids be the same substance and why?
Solids 1 and 2 could be the same substance. Even though they do not have the same melting point, they have the same mass.
Solids 2 and 3 could be the same substance. Even though they do not have the same mass, they have the same melting point and color.
Solids 1, 2, and 3 could all be the same substance. Even though they do not all have the same mass and melting point, they have the same color.
Solids 1, 2, and 3 cannot be the same substance because they have different combinations of color, melting point, and mass.
