The tendency of a liquid to minimize its surface area is called:
capillary action.
viscosity.
surface tension.
vaporization.
The measure of the resistance to the flow of a liquid is called:
vapor pressure.

condensation.
Which intermolecular force is present in all molecules and atoms?
dispersion forces
dipole-dipole forces
hydrogen bonding
none of the above
Select all the physical properties true for ionic compounds.
high melting and boiling points
low melting and boiling points
can dissolve in water
cannot dissolve in water
can dissolve in organic solvents
Select all the physical properties true for covalent substances.
high melting and boiling points
low melting and boiling points
can dissolve in water
cannot dissolve in water
can dissolve in organic solvents
Ionic compounds can conduct electricity in molten and aqueous states because
electrons are free to move.
ions are free to move.
atoms are free to move.
protons are free to move.
Many covalent substances are volatile liquids or gases at room temperature because
the intermolecular forces of attraction holding the molecules together are weak.
the covalent bonds within the molecules are easily broken.
the electrostatic attraction between ions is a weak force that can be overcome easily.
they consists of simple molecules that do not dissolve in water but dissolve in organic solvents.
Why most covalent substances do not conduct electricity in all states?
no electrons
no free-moving charged particles
too strong covalent bonds
no electron gain or loss between atoms

melting
freezing
boiling (vaporization)
condensation

100 degrees C
120 degrees C
140 degrees C
160 degrees C
