Absolute Zero
States of Matter & Gas Laws
K
The lowest possible temperature, at which particles retain only their irreducible quantum zero-point motion.
0 K = −273.15 °C
Amorphous Solid
States of Matter & Gas Laws
Dimensionless
A solid whose particles lack long-range order, showing only the short-range regularity characteristic of a frozen liquid.
Anisotropy
States of Matter & Gas Laws
Dimensionless
The dependence of a physical property on the direction in which it is measured.
Average Kinetic Energy
States of Matter & Gas Laws
J
The mean translational kinetic energy of the particles in a sample, dependent only on absolute temperature.
KE = (3/2)kT per molecule
Avogadro's Law
States of Matter & Gas Laws
L/mol
Equal volumes of all gases at the same temperature and pressure contain equal numbers of molecules.
V ∝ n
