A polymer that softens on heating and hardens again on cooling, reversibly and repeatedly.
Chemical Bonding & Molecular StructureThree-Centre Two-Electron Bond
A bond in which a single pair of electrons is shared between three atoms rather than two.
States of Matter & Gas LawsVapour Pressure
The pressure exerted by a vapour in dynamic equilibrium with its liquid or solid at a given temperature.

Biochemistry & Polymer ChemistryDegree of Polymerisation
The number of monomer units in an average polymer chain.
Foundations of ChemistryDimensional Analysis
A calculation method that tracks and cancels units through a chain of conversion factors to reach the required quantity.
Thermochemistry & ThermodynamicsEnthalpy of Reaction
The heat absorbed or released when a reaction occurs at constant pressure in the molar amounts of the balanced equation.
Foundations of ChemistryExtensive Property
A property whose value is directly proportional to the quantity of matter in the sample.
Atomic Structure & PeriodicityGroup
A vertical column of the periodic table whose members share the same valence electron configuration.
States of Matter & Gas LawsIdeal Gas Law
The equation of state relating the pressure, volume, amount and absolute temperature of an ideal gas.
Chemical EquilibriumLe Chatelier's Principle
When a system at equilibrium is disturbed, it responds in the direction that partially opposes the disturbance.
Acids, Bases & SaltsLewis Theory
The theory defining an acid as an electron pair acceptor and a base as an electron pair donor.
Organic ChemistryOrganic Chemistry
The study of the structure, properties, composition and reactions of carbon-containing compounds.
Chemical Kinetics & CatalysisPre-exponential Factor
The constant A in the Arrhenius equation, representing the frequency of appropriately oriented collisions.
Stoichiometry & Chemical ReactionsStoichiometric Mixture
A mixture of reactants present in exactly the proportions required by the balanced equation, with no reactant in excess.
