WHICH OF THE FOLLOWING STATEMENT IS TRUE?

Solids which have high boiling points have stronger forces of attraction between their particles than those which have low melting points.
Liquids which have high melting points have stronger forces of attraction between their particles than those which have low melting points.
Gas with high melting points have stronger forces of attraction between their particles than those which have low melting points.
WHEN YOU MIX OIL AND WATER, OIL FLOATS ABOVE WATER EVEN THEY ARE BOTH LIQUID. WHY?
because they have different composition
because they have differences in molecules.
because they have different densities
becuase they have different specific gravity
WHAT DO YOU CALL THE RATIO OF THE DENSIY OF A SUBSTANCE TO THAT DENSITY OF WATER?
boiling point
melting point
specific gravity
mixture
