Study Notes

Surface tension is the measure of the elastic force in the surface of a liquid.
Vapor pressure is the pressure exerted by the gas in equilibrium with a liquid in a closed container at a given temperature.
Viscosity is a measure of the resistance of fluid to flow.
Boiling point is the temperature at which the liquid converts into a gas.
Capillary action is the tendency of a liquid to rise in narrow tubes or be drawn into small openings.
Molar heat of vaporization is the energy required to vaporize 1 mole of a liquid at a given temperature.

Crystalline solids have a crystal lattice structure, with a combination of unit cells forming a network.
Amorphous solids have a random orientation of particles.
Crystalline solids have distinct melting points, are generally incompressible, and have a repeating geometric structure.
Amorphous solids melt gradually over a range of temperature, can be compressed, and have a random arrangement of particles.

Crystal lattice is a combination of unit cells forming a network.
Unit cell is the smallest repeating structure.
Crystalline solids have distinct melting points because applying heat breaks the bonds at the same time.
They are generally incompressible because of the repeating geometric structure.

Amorphous solids have a random orientation of particles.
They melt gradually over a range of temperature because the bonds do not break at once.
They can be appreciably compressed because of the random arrangement of particles.

Ionic crystals are made of different-sized particles, have high melting points and boiling points, and are not good conductors of heat and electricity as solids.
Molecular crystals are held by weak London dispersion forces, dipole-dipole forces or hydrogen bonds, have low melting points, and are poor conductors of heat and electricity.
Covalent crystals are extremely strong and very hard to break, have high melting points, and are poor conductors of heat and electricity.
Metallic crystals are good conductors of heat and electricity, vary in melting points and hardness, and are malleable and ductile.
