States of Matter & Gas Laws
Dimensionless
A point defect in which equal numbers of cations and anions are missing from their lattice sites.
Simple Cubic
States of Matter & Gas Laws
Dimensionless
A crystal arrangement with particles only at the eight corners of a cubic unit cell.
1 atom per cell, 52% packing
Solid State
States of Matter & Gas Laws
Dimensionless
The state of matter in which particles are held in fixed positions, giving a definite shape and volume.
Sublimation
States of Matter & Gas Laws
kJ/mol
The direct conversion of a solid into a vapour without passing through the liquid state.
ΔH_sub = ΔH_fus + ΔH_vap
Supercritical Fluid
States of Matter & Gas Laws
K, Pa
A substance held above both its critical temperature and critical pressure, where liquid and gas phases are indistinguishable.
T > T_c and p > p_c
Surface Tension
States of Matter & Gas Laws
N/m
The energy required to increase the surface area of a liquid by unit amount, arising from unbalanced intermolecular forces at the surface.
γ = F / L
