Factory pattern should be used when: - a framework delegate the creation of objects derived from a common superclass to the factory - we need flexibility in adding new types of objects that must be created by the class. Along with singleton pattern the factory is one of the most used patterns.
In thermodynamics, the term exothermic process (exo- : outside) describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), electricity (e.g. a battery), or sound (e.g. explosion heard when burning hydrogen).
Free energy. Free energy. a thermodynamic term used to describe the energy that may be extracted from a system at constant temperature and pressure. In biological systems the most important relationship is: _G = RTln(keq), where keq is an equilibrium constant. The amount of energy available for reactions to occur.
