The thermodynamic properties of materials are intensive thermodynamic parameters which are specific to a given material. Examples for a simple 1-component system are: In thermodynamics, there are a large number of equations relating the various thermodynamic quantities. ...
The laws of Thermodynamics in principle describe the specifics for the transport of heat and work in thermodynamic processes. ...
The zeroth law of thermodynamics may be succintly stated as: If two thermodynamic systems A and B are in thermal equilibrium, and B and C are also in thermal equilibrium, then A and C are in thermal equilibrium. ...
Conservation of energy (the first law of thermodynamics) is one of several conservation laws. ...
The second law of thermodynamics, in a concise form, states that the total entropy of any thermodynamically isolated system tends to increase over time, approaching a maximum value. // General description In a general sense, the second law says that the differences between systems in contact with each other tend to...
The third law of thermodynamics was developed by Walther Nernst and is thus sometimes referred to as Nernsts theorem. ...
Thermodynamic potentials Maxwell relations Bridgmans equations Exact differential (edit) In thermodynamics, the internal energy of a system is expressed in terms of pairs of conjugate variables such as pressure/volume or temperature/entropy. ...
Pressure (symbol: p) is the force per unit area acting on a surface in a direction perpendicular to that surface. ...
Volume, also called capacity, is a quantification of how much space an object occupies. ...
Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ...
For other senses of the term, see entropy (disambiguation). ...
The precise meaning of the term chemical potential depends on the context in which it is used. ...
The particle number, N, is the number of so called elementary particles (or elementary constituents) of a thermodynamical system. ...
This article needs to be cleaned up to conform to a higher standard of quality. ...
The internal energy of a system (abbreviated E or U) is the total kinetic energy due to the motion of molecules (translational, rotational, vibrational) and the total potential energy associated with the vibrational and electric energy of atoms within molecules or crystals. ...
This page develops the Helmholtz free energy from the point of view of thermal and statistical physics. ...
Enthalpy (symbolized H, also called heat content) is the sum of the internal energy of matter and the product of its volume multiplied by the pressure. ...
In thermodynamics the Gibbs free energy is a thermodynamic potential and is therefore a state function of a thermodynamic system. ...
The specific heat capacity (symbol c or s, also called specific heat) of a substance is defined as heat capacity per unit mass. ...
Fluid Dynamics Compressibility (physics) is a measure of the relative volume change of fluid or solid as a response to a pressure (or mean stress) change: . For a gas the magnitude of the compressibility depends strongly on whether the process is adiabatic or isothermal, while this difference is small in...
In physics, thermal expansion is the tendency of matter to increase in volume or pressure when heated. ...
Maxwells relations are a set of equations in Thermodynamics which are derivable from the definitions of the four thermodynamic potentials. ...
In Thermodynamics, Bridgmans Thermodynamic equations is actually a method of generating a large number of thermodynamic identities involving a number of thermodynamic quantities. ...
In mathematics, both in vector calculus and in differential topology, the concepts of closed form and exact form are defined for differential forms, by the equations dα = 0 for a given form α to be a closed form, and α = dβ for an exact form, with α given and β...
