the state of equilibrium

62Chemical equilibrium — In a chemical reaction, chemical equilibrium is the state in which the concentrations of the reactants and products have not yet changed with time. It occurs only in reversible reactions, and not in irreversible reactions. Usually, this state… …
63Mechanical equilibrium — A pendulum in a stable equilibrium (left) and unstable equilibrium (right) A standard definition of static equilibrium is: A system of particles is in static equilibrium when all the particles of the system are at rest and the total force on each …
64Thermodynamic equilibrium — In thermodynamics, a thermodynamic system is said to be in thermodynamic equilibrium when it is in thermal equilibrium, mechanical equilibrium, and chemical equilibrium. The local state of a system at thermodynamic equilibrium is determined by… …
65Punctuated equilibrium — is a theory of evolutionary biology which states that most sexually reproducing populations experience little change for most of their geological history, and that when phenotypic evolution does occur, it is localized in rare, rapid events of… …
66General equilibrium — theory is a branch of theoretical microeconomics. It seeks to explain the behavior of supply, demand and prices in a whole economy with several or many markets. It is often assumed that agents are price takers and in that setting two common… …
67Steady state (chemistry) — For other uses of the term steady state, see steady state (disambiguation) In chemistry, a steady state is a situation in which all state variables are constant in spite of ongoing processes that strive to change them. For an entire system to be… …
68Vapor-liquid equilibrium — Vapor liquid equilibrium, abbreviated as VLE by some, is a condition where a liquid and its vapor (gas phase) are in equilibrium with each other, a condition or state where the rate of evaporation (liquid changing to vapor) equals the rate of… …
69Tragedy of the commons — Cows on Selsley Common. The tragedy of the commons is one way of accounting for overexploitation. The tragedy of the commons is a dilemma arising from the situation in which multiple individuals, acting independently and rationally consulting… …
70Quasistatic equilibrium — is the quasi balanced state of a thermodynamic system near to thermodynamic equilibrium in some sense or degree. A process is called quasi static when it follows a succession of equilibrium states; the surroundings may be irreversibly altered… …
