The stronger the molecular forces the $($higher$,$ lower$)$

the melting point,

the boiling point.

How is the electronegativity related to the strength of the intermolecular forces?

What kind of interactions are present in nonpolar molecules?

Which one has a lower melting point: a solution or a solvent?

$2.$ "Like dissolves like". Would you expect pentene, $C_5{H}_{12},$ to be soluble in $H_{2}O?$ Explain.

$3.$ The volume of unknown liquid is $34\mathrm{.}6mL$ and its mass is $29\mathrm{.}65$ grams. Calculate the density of the liquid.
