Equilibrium constant, a quantity characterizing a chemical equilibrium in a chemical reaction; Partition equilibrium, a type of chromatography that is typically used in GC; Quasistatic equilibrium, the quasi-balanced state of a thermodynamic system near to equilibrium in some sense or degree; Schlenk equilibrium, a chemical equilibrium named ...
Consequently, the object is in a state of static mechanical equilibrium. In classical mechanics, a particle is in mechanical equilibrium if the net force on that particle is zero. [1]: 39 By extension, a physical system made up of many parts is in mechanical equilibrium if the net force on each of its individual parts is zero. [1]: 45–46 [2]
A system in which all processes of change have gone practically to completion is considered in a state of thermodynamic equilibrium. [3] The thermodynamic properties of a system in equilibrium are unchanging in time. Equilibrium system states are much easier to describe in a deterministic manner than non-equilibrium states.
Mechanochemistry (or mechanical chemistry) is the initiation of chemical reactions by mechanical phenomena. Mechanochemistry thus represents a fourth way to cause chemical reactions, complementing thermal reactions in fluids, photochemistry, and electrochemistry. Conventionally mechanochemistry focuses on the transformations of covalent bonds ...
physical chemistry, dealing with physical processes and their relations in the science of physical chemistry; physical oceanography, is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters; psychophysics, the science of physical relations in psychology
M. Zemansky also distinguishes mechanical, chemical, and thermal equilibrium. He then writes: "When the conditions for all three types of equilibrium are satisfied, the system is said to be in a state of thermodynamic equilibrium". [36] P.M. Morse writes that thermodynamics is concerned with "states of thermodynamic equilibrium". He also uses ...
A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium.
If two systems are both in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. [ 4 ] Though this version of the law is one of the most commonly stated versions, it is only one of a diversity of statements that are labeled as "the zeroth law".
