Capillary Action
States of Matter & Gas Laws
m
The spontaneous rise or fall of a liquid in a narrow tube, driven by the balance between adhesion and cohesion.
h = 2γcosθ / ρgr
Charles's Law
States of Matter & Gas Laws
m³/K
At constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature.
V₁ / T₁ = V₂ / T₂
Combined Gas Law
States of Matter & Gas Laws
Various
The relation linking pressure, volume and temperature for a fixed amount of gas undergoing a change of state.
p₁V₁ / T₁ = p₂V₂ / T₂
Compressibility Factor
States of Matter & Gas Laws
Dimensionless
The ratio of the actual molar volume of a gas to that predicted by the ideal gas law.
Z = pV / nRT
Condensation
States of Matter & Gas Laws
kJ/mol
The change of a substance from the gaseous to the liquid state, accompanied by the release of latent heat.
Critical Point
States of Matter & Gas Laws
K, Pa
The unique combination of temperature and pressure at which the liquid and gas phases of a substance become indistinguishable.
(T_c, p_c)
Critical Temperature
States of Matter & Gas Laws
K
The temperature above which a gas cannot be liquefied by pressure alone, however great.
T_c = 8a / 27Rb
Crystal Defect
States of Matter & Gas Laws
Dimensionless
Any irregularity that interrupts the perfectly ordered arrangement of particles in a crystal.
Crystalline Solid
States of Matter & Gas Laws
Dimensionless
A solid in which the constituent particles are arranged in a regular, repeating three-dimensional pattern extending over long distances.
