PROPERTIES OF LIQUIDS & INTERMOLECULAR FORCES

The resistance of liquids to flow; “the thickness”

• VISCOSITY

• SURFACE TENSION

• CAPILLARY ACTION

• ADHESIVE FORCES

It is the energy required to break through the surface or to disrupt a liquid drop and make the drop spread out like a film.

• VISCOSITY

• SURFACE TENSION

• CAPILLARY ACTION

• ADHESIVE FORCES

These are forces between liquid molecules

• COHESIVE FORCES

• COERSIVE FORCES

• ADHESIVE FORCES

• ADVERSIVE FORCES

These are forces between liquid molecules and another substance.

• COHESIVE FORCES

• COERSIVE FORCES

• ADHESIVE FORCES

• ADVERSIVE FORCES

It is the rise of liquids up narrow tubes and other surfaces

• CAPILLARITY ACTION

• CAPILLARY ACTION

• BOTH ANSWERS ARE CORRECT

• NONE OF THE CHOICES

In what situation does DIPOLE -DIPOLE FORCES are stronger?

• If two molecules are of comparable size and shape, dipole–dipole interactions will likely be the dominating force.

• If one molecule is much larger than another, dipole–dipole interactions will likely be the dominating force.

• If positive ends of polar molecules are oriented to negatively charged anions, dipole–dipole interactions will likely be the dominating force.

• If negative ends of polar molecules are oriented to positively charged cations, dipole–dipole interactions will likely be the dominating force.

In which situation does DISPERSION FORCES are strongest?

• If two molecules are of comparable size and shape, dispersion forces will likely determine its physical properties.

• If one molecule is much larger than another, dispersion forces will likely determine its physical properties.

• If negative ends of polar molecules are oriented to positively charged cations, dispersion forces will likely determine its physical properties.

• If positive ends of polar molecules are oriented to negatively charged anions, dispersion forces will likely determine its physical properties.

Water (H₂o) is a _____ covalent molecule.

• POLAR

• NON -POLAR

• BOTH POLAR & NON -POLAR

• NEITHER POLAR NOR NON -POLAR

Which is NOT TRUE about viscosity?

• Viscosity increases with stronger intermolecular forces.

• Viscosity increases with decreasing temperature.

• Viscosity is the resistance of liquids to flow.

• Viscosity increases with increasing temperature

Which among the elements DOESN'T HAVE THE STRONGEST BONDING with hydrogen?

• Nitrogen

• Oxygen

• Fluorine

• Boron
