Thermodynamics, science of the relationship between heat, work, temperature, and energy.In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work.

: a measure of the unavailable energy in a closed thermodynamic system that is also usually considered to be a measure of the system’s disorder and that is a property of the system’s state and is related to it in such a manner that a reversible change in heat in the system produces a change in the measure which varies directly with the heat change.

A parametric crossover model is adapted to represent the thermodynamic properties of pure D2O in the extended critical region. The crossover equation of state for D2O incorporates scaling laws.

1. 2. 3 The Concept of a “State”. The thermodynamic state of a system is defined by specifying values of a set of measurable properties sufficient to determine all other properties. For fluid systems, typical properties are pressure, volume and temperature. More complex systems may require the specification of more unusual properties.
