Thermodynamic equilibrium print that page

In thermodynamics , a thermodynamic system is said to be in thermodynamic equilibrium when it is in thermal equilibrium , mechanical equilibrium , radiative equilibrium , and chemical equilibrium . The word equilibrium means a state of balance. In a state of thermodynamic equilibrium

Thermodynamic temperature print that page

IceBlockNearJoekullsarlon

of matter . These motions comprise the kinetic energy in a substance. More specifically, the thermodynamic temperature of any bulk quantity of matter is the measure of the average kinetic energy of a certain kind of vibrational motion of its constituent particles called translational motions

Vapor–liquid equilibrium print that page

The concentration of a vapor in contact with its liquid, especially at equilibrium , is often in terms of vapor pressure , which could be a partial pressure (part of the total gas pressure) if any other gas(es) are present with the vapor. The equilibrium vapor pressure of a liquid is usually

Thermodynamic system print that page

Example

A thermodynamic system is a precisely defined macroscopic region of the universe, often called a physical system , that is studied using the principles of thermodynamics . All spac[[File: [[File: ]]]]e in the universe outside the thermodynamic system is known as the surroundings , the

Thermodynamic equations print that page

One of the fundamental thermodynamic equation, is the description of thermodynamics work in analogy to mechanical work , or weight lifted through an elevation against gravity, as defined in 1824 by French physicist Sadi Carnot . Carnot used the phrase motive power for work. In the footnotes

Conjugate variables (thermodynamics) print that page

terms of pairs of conjugate variables such as temperature/entropy or pressure/volume. In fact all thermodynamic potentials are expressed in terms of conjugate pairs. For a mechanical system, a small increment of energy is the product of a force times a small displacement. A similar situation

Chemical equilibrium print that page

In a chemical reaction , chemical equilibrium is the state in which the concentrations of the reactants and products have not yet changed with time. It occurs only in reversible reactions , and not in irreversible reactions. Usually, this state results when the forward reaction proceeds

Thermodynamic free energy print that page

The thermodynamic free energy is the amount of work that a thermodynamic system can perform. The concept is useful in the thermodynamics of chemical or thermal processes in engineering and science. The free energy is the internal energy of a system less the amount of energy that cannot
