Item SC064007: Two liquids with the same density and color but different boiling points are different substances. (This item uses a table that lists properties of the liquids.)
A student determines the volume, density, and boiling point of three colorless liquids and lists them in the table below.
|
Volume (mL) |
Density (g/mL) |
Boiling Point (°C) |
Color | |
| Liquid 1 | 10 | 0.79 | 56 | colorless |
| Liquid 2 | 50 | 0.79 | 78 | colorless |
| Liquid 3 | 10 | 1.0 | 100 | colorless |
Could any of the liquids be the same substance?
- Liquids 1 and 2 could be the same substance.
- Liquids 1 and 3 could be the same substance.
- All of the liquids could be the same substance.
- None of the liquids could be the same substance.
