Which property is affected by strong intermolecular forces?

High boiling point of the substance.

High volatility in gases.

High electrical conductivity.

Low melting point of the substance.

1

What increases with stronger intermolecular forces in liquids?

Viscosity of the liquid increases significantly.

Surface tension decreases greatly.

Density decreases in all cases.

Evaporation rate increases.

1

Why do polar substances mix better with water?

Non-polar substances react faster with water.

Water's temperature increases with mixing.

Polar molecules repel each other in solution.

Polar molecules interact strongly with water's dipoles.

How do intermolecular forces affect solids?

Stronger forces lead to more rigid structures.

Solids become liquid at high temperatures.

Intermolecular forces have no effect.

Weaker forces produce tighter packing in solids.
