• The mixture had a lower volume than expected

• The volume of the mixture was what I expected

Why did the particle model of matter better explain water/ethanol mixture?

• the model showed the colors of the molecules. water was blue and ethanol was red.

• The model showed the molecules moving

• The model showed the mixture changes colors after mixed

• The model showed the smaller water molecules fitting into the gaps made by the larger ethanol molecules.
