Emulsion
Colloidal suspension of a liquid in a liquid.
Background Radiation
Ratiation extraneous to an experiment. Usually the low-level natural radiation form cosmic rays and trace radioactive substances present in our environment.
Quantum Mechanics
Mathematical method of treating particles on the basis of quantum theory, which assumes that energy (of small particles) is not infinitely divisible.
Flash Point
The temperature at which a liquid will yield enough flamable vapour to ignite. There are various recognized industrial testing methods, therefore the method used must be stated.
Critical Point
The combination of critical temperature and critical pressure of a substance.
Oxidizing Agent
The substance that oxidizes another substance and is reduced.
Carbonium ion
An orgainic ion carrying a positive charge on a carbon atom.
Calorie
The amount of heat required to raise the temperature of one gram of water from 14.5°C to 15.5°C. 1 calorie = 4.184 joules.
Differential Scanning Calorimetry (DSC)
A technique for measuring the temperature, direction, and magnitude of thermal transitions in a sample material by heating/cooling and comparing the amount of energy required to maintain its rate of temperature increase or decrease with an inert reference material under similar conditions.
Energy
The capacity to do work or transfer heat.
