The table shows measurements for one sample of a pure substance in three states. No material is lost between measurements.
| State | Mass in g\mathrm{g}g | Volume in cm3\mathrm{cm^3}cm3 |
|---|---|---|
| X | 48 | 60 |
| Y | 48 | 50 |
| Z | 48 | 30000 |
In X, the particles vibrate about fixed positions. Which conclusion is correct?
Y is the liquid; its molecules are farther apart than in X.
Z is the liquid; its molecules are closer on average than in X.
Y is the liquid; its molecules are closer on average than in X.
