The process of breaking down organic material; reduction of the net energy level and change in physical and chemical composition of organic material.
Industry:Energy
Under the First Law of Thermodynamics, efficiency is the ratio of work or energy output to work or energy input, and cannot exceed 100 percent. Efficiency under the Second Law of Thermodynamics is determined by the ratio of the theoretical minimum energy that is required to accomplish a task relative to the energy actually consumed to accomplish the task. Generally, the measured efficiency of a device, as defined by the First Law, will be higher than that defined by the Second Law.
Industry:Energy
The amount of work accomplished by electrical power, usually measured in kilowatt-hours (kWh). One kWh is 1,000 Watts and is equal to 3,413 Btu.
Industry:Energy
The flow of electrical energy (electricity) in a conductor, measured in amperes.
Industry:Energy
An elementary particle of an atom with a negative electrical charge and a mass of 1/1837 of a proton; electrons surround the positively charged nucleus of an atom and determine the chemical properties of an atom.
Industry:Energy
A chemical change in a substance that results from the passage of an electric current through an electrolyte. The production of commercial hydrogen by separating the elements of water, hydrogen, and oxygen, by charging the water with an electrical current.
Industry:Energy
A nonmetallic (liquid or solid) conductor that carries current by the movement of ions (instead of electrons) with the liberation of matter at the electrodes of an electrochemical cell.
Industry:Energy
Energy generated from an electromagnetic field produced by an electric current flowing through a superconducting wire kept at a specific low temperature.
Industry:Energy
The capability of doing work; different forms of energy can be converted to other forms, but the total amount of energy remains the same.
