Terminology "T"
- Temperature
- A measure of the intensity of heat, i.e. the hotness or coldness of a
sample. or object.
- Ternary Acid
- A ternary compound containing H, O, and another element, often a nonmetal.
- Ternary Compound
- A compound consisting of three elements; may be ionic or covalent.
- Tetrahedral
- A term used to describe molecules and polyatomic ions that have one atom
in center and four atoms at the corners of a tetrahedron.
- Theoretical Yield
- Maximum amount of a specified product that could be obtained from specified
amounts of reactants, assuming complete consumption of limiting reactant
according to only one reaction and complete recovery of product. (Compare with
Actual Yield)
- Thermal Cracking
- Decomposition by heating a substance in the presence of a catalyst and in
the absence of air.
- Thermodynamics
- The study of the energy transfers accompanying physical and chemical
processes.
- Thermonuclear Energy
- Energy from nuclear fusion reactions.
- Third Law of Thermodynamics
- The entropy of a hypothetical pure, perfect, crystalline sustance at
absolute zero temperature is zero.
- Titration
- A Procedure in which one solution is added to another solution until the
chemical reaction between the two solutes is complete; the concentration of one
solution is known and that of the other is unknown.
- Total Ionic Equation
- Equation for a chemical reaction written to show the predominant form of
all species in aqueous solution or in contact with water.
- Transition State Theory
- Theory of reaction rates that states that reactants pass through
high-energy transition states before forming products.
- Tyndall Effect
- The scattering of light by colloidal particles.
