A thermodynamic state (from Latin status = to stand) is the state of a thermodynamic system as described by its properties, namely particular thermodynamic parameters. A minimum number of parameters are necessary to specify the state of the system.

The state of the thermodynamic system can be thought of as an optimal ensemble of thermodynamic parameters, namely temperature, pressure, density, composition, etc., which characterize the system, but neither by its surroundings nor by its history. The number of properties required to fix the state of a system is given by the state postulate, which dictates that the state of a simple compressible system is completely specified by two independent, intensive properties. 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. ...

Jump to: navigation, search Density (symbol: ρ - Greek: rho) is a measure of mass per unit of volume. ... Composition deals with the bits and pieces that make up things. ... In physics and chemistry, an intensive quantity (also referred to as an intensive variable) is a physical quantity whose value does not depend on the amount of the substance for which it is measured. ...
