The volumes or weights of two mixed liquids do not always sum additively due to intermolecular packing
the verdict
SUPPORTED
the evidence backs this
confidence 75/100
The volumes of mixed liquids frequently exhibit nonadditive behavior, resulting in positive or negative excess molar volumes due to intermolecular interactions and packing effects.
