Word Origin for equilibrium
Word Origin and History for equilibrium
- 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.
- 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.
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.)
