Adiabatic process

An adiabatic process (adiabatic) is a type of thermodynamic process that occurs without transferring heat or mass between the thermodynamic system and its environment.

See Internal pressure and Adiabatic process

Carbon dioxide

Carbon dioxide is a chemical compound with the chemical formula.

Compressibility factor

In thermodynamics, the compressibility factor (Z), also known as the compression factor or the gas deviation factor, describes the deviation of a real gas from ideal gas behaviour.

See Internal pressure and Compressibility factor

Exact differential

In multivariate calculus, a differential or differential form is said to be exact or perfect (exact differential), as contrasted with an inexact differential, if it is equal to the general differential dQ for some differentiable function Q in an orthogonal coordinate system (hence Q is a multivariable function whose variables are independent, as they are always expected to be when treated in multivariable calculus).

Francis Sears

Francis Weston Sears (October 1, 1898 – November 12, 1975) was an American physicist.

Frederick G. Keyes

Frederick George Keyes (June 24, 1885 – April 14, 1976) was an American physical chemist.

Ideal gas law

The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas.

See Internal pressure and Ideal gas law

Internal energy

The internal energy of a thermodynamic system is the energy contained within it, measured as the quantity of energy necessary to bring the system from its standard internal state to its present internal state of interest, accounting for the gains and losses of energy due to changes in its internal state, including such quantities as magnetization. Internal pressure and internal energy are thermodynamic properties.

International System of Units

The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités), is the modern form of the metric system and the world's most widely used system of measurement.

James Prescott Joule

James Prescott Joule (24 December 1818 11 October 1889) was an English physicist, mathematician and brewer, born in Salford, Lancashire.

Joule expansion

The Joule expansion (a subset of free expansion) is an irreversible process in thermodynamics in which a volume of gas is kept in one side of a thermally isolated container (via a small partition), with the other side of the container being evacuated.

See Internal pressure and Joule expansion

Kinetic energy

In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion.

See Internal pressure and Kinetic energy

Maxwell relations

Flow chart showing the paths between the Maxwell relations. P is pressure, T temperature, V volume, S entropy, \alpha coefficient of thermal expansion, \kappa compressibility, C_V heat capacity at constant volume, C_P heat capacity at constant pressure. Maxwell's relations are a set of equations in thermodynamics which are derivable from the symmetry of second derivatives and from the definitions of the thermodynamic potentials.

Partial derivative

In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary).

See Internal pressure and Partial derivative

Pascal (unit)

The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI).

See Internal pressure and Pascal (unit)

Perfect gas

In physics and engineering, a perfect gas is a theoretical gas model that differs from real gases in specific ways that makes certain calculations easier to handle.

Peter Atkins

Peter William Atkins (born 10 August 1940) is an English chemist and a Fellow of Lincoln College at the University of Oxford.

Potential energy

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.

See Internal pressure and Potential energy

Pressure

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Internal pressure and Pressure are thermodynamic properties.

See Internal pressure and Pressure

Specific heat capacity

In thermodynamics, the specific heat capacity (symbol) of a substance is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. Internal pressure and specific heat capacity are thermodynamic properties.

See Internal pressure and Specific heat capacity

Temperature

Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Internal pressure and Temperature are thermodynamic properties.

See Internal pressure and Temperature

Thermodynamic equations

Thermodynamics is expressed by a mathematical framework of thermodynamic equations which relate various thermodynamic quantities and physical properties measured in a laboratory or production process.

See Internal pressure and Thermodynamic equations

Van der Waals equation

The van der Waals equation, named for its originator, the Dutch physicist Johannes Diderik van der Waals, is an equation of state that extends the ideal gas law to include the non-zero size of gas molecules and the interactions between them (both of which depend on the specific substance).

See Internal pressure and Van der Waals equation

Volume (thermodynamics)

In thermodynamics, the volume of a system is an important extensive parameter for describing its thermodynamic state. Internal pressure and volume (thermodynamics) are thermodynamic properties.

Water

Water is an inorganic compound with the chemical formula.
