5. The relative randomness of molecules in the states of matter is best indicated by

Solid > Liquids > Gas

Liquid > Gas > Solid

Liquid > Solid > Gas

Gas > Liquid > SolidAns

6. Whether or not two liquids are miscible is determined by

Molecular Size : Molecules of similar sizes tend to mix together

Density : Liquids of simliar densities usually mix well together

Polarity : Polar and nonpolar liquids are not miscible while polar liquids can usually be mixed with each other Ans

All of the above factors directly affect miscibility
