21chemical compound — Introduction any substance composed of identical molecules consisting of atoms (atom) of two or more chemical elements (chemical element). All the matter in the universe is composed of the atoms of more than 100 different chemical elements …
22Counter-intelligence — This article is a subset article of intelligence cycle security. National intelligence programs, and, by extension, the overall defenses of nations, are vulnerable to attack. It is the role of intelligence cycle security to protect the process… …
23Principle of minimum energy — The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at …
24Entropy — This article is about entropy in thermodynamics. For entropy in information theory, see Entropy (information theory). For a comparison of entropy in information theory with entropy in thermodynamics, see Entropy in thermodynamics and information… …
25Thermodynamic temperature — is the absolute measure of temperature and is one of the principal parameters of thermodynamics. Thermodynamic temperature is an “absolute” scale because it is the measure of the fundamental property underlying temperature: its null or zero point …
26Determination of equilibrium constants — Equilibrium constants are determined in order to quantify chemical equilibria. When an equilibrium constant is expressed as a concentration quotient, it is implied that the activity quotient is constant. In order for this assumption to be valid… …
27Dissociation (chemistry) — For other uses, see dissociation (psychology) and dissociation (neuropsychology). Dissociation in chemistry and biochemistry is a general process in which ionic compounds (complexes, or salts) separate or split into smaller particles, ions, or… …
28List of Statutory Instruments of the United Kingdom, 1997 — This is a complete list of all 1840 Statutory Instruments published in the United Kingdom in the year 1997. NOTOC 1 100* Education (Recognised Bodies) Order 1997 S.I. 1997/1 * Bedfordshire and Hertfordshire Ambulance and Paramedic Service… …
29Life Sciences — ▪ 2009 Introduction Zoology In 2008 several zoological studies provided new insights into how species life history traits (such as the timing of reproduction or the length of life of adult individuals) are derived in part as responses to… …
30Van der Waals equation — The van der Waals equation is an equation of state for a fluid composed of particles that have a non zero size and a pairwise attractive inter particle force (such as the van der Waals force.) It was derived by Johannes Diderik van der Waals in… …
