A condition in which all acting influences are canceled by others, resulting in a stable, balanced, or unchanging system. 2. Mental or emotional balance; poise. 3.

Chemistry 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. [Latin aequil  brium : aequi-, equi- + lbra, balance.] |

4. (Physics / General Physics) Physics a state of rest or uniform motion in which there is no resultant force on a body
5. (Chemistry) Chem the condition existing when a chemical reaction and its reverse reaction take place at equal rates
6. (Physics / General Physics) Physics the condition of a system that has its total energy distributed among its component parts in the statistically most probable manner
7. (Life Sciences & Allied Applications / Physiology) Physiol a state of bodily balance, maintained primarily by special receptors in the inner ear

[from Latin aequilībrium, from aequi- equi- + lībra pound, balance]
| equilibrium (kw-lbr-m) Plural equilibriums or equilibria 1. 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.2. 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. |
