(chemistry) A measure of the relative concentrations of the reactants and products of a reversible reaction at equilibrium

(physics) an equilibrium in which a small disturbance causes it to move further away from the original state

(physics) an equilibrium in which a small disturbance causes it to move back to the original state

(chemistry) The state of a reversible reaction in which the rates of the forward and reverse reactions are the same

(physics) The state in which a solid or liquid body has relaxed into the shape that it would have if it were a calm (equilibrium) liquid. Mathematically, this means a sphere if it is not distorted by another body and is not rotating, but an oblate or scalene ellipsoid if rotating moderately, and piriform if rotating beyond the ellipsoidal limit. When in contact with another object, such as oil drops on or in water, other shapes occur.
