noun plural -riums or -ria (-rɪə)
- a stable condition in which forces cancel one another
- a state or feeling of mental balance; composure
- any unchanging condition or state of a body, system, etc, resulting from the balance or cancelling out of the influences or processes to which it is subjectedSee thermodynamic equilibrium

- chem the condition existing when a chemical reaction and its reverse reaction take place at equal rates
- physics the condition of a system that has its total energy distributed among its component parts in the statistically most probable manner
- physiol a state of bodily balance, maintained primarily by special receptors in the inner ear
- the economic condition in which there is neither excess demand nor excess supply in a market
- A condition in which all influences acting upon it are canceled by others, resulting in a stable, balanced, or unchanging system.
- The state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time.dynamic equilibrium
- Mental or emotional balance.
Plural equilibriums equilibria
- Physics The state of a body or physical system that is at rest or in constant and unchanging motion. A system that is in equilibrium shows no tendency to alter over time.♦ If a system is in static equilibrium, there are no net forces and no net torque in the system.♦ If a system is in stable equilibrium, small disturbances to the system cause only a temporary change before it returns to its original state.
- Chemistry The state of a reversible chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products remains the same.
In economics, a state of the economy in which for every commodity or service (including labor), total supply and demand are exactly equal. Equilibrium is never actually attained; it is approximated by movements of the market.
A condition in which all influences acting cancel each other, so that a static or balanced situation results. In physics, equilibrium results from the cancellation of forces acting on an object. In chemistry, it occurs when chemical reactions are proceeding in such a way that the amount of each substance in a system remains the same. (See chemical equilibrium.)
