The density and the specific volume of a simple compressible system are known. What is the number of additional intensive, independent properties needed to fix the state of this system?

Answer:

We don't need more properties according to the State Postulate.

Step-by-step explanation:

Any system has numerous properties. However, only a small subset must be known to define its state, as described by the STATE POSTULATE:

The state of a simple compressible system is completely specified by two independent, intensive properties.

Thermodynamic properties can be divided into two general classes:

Extensive properties: An extensive property is dependent upon the amount of mass present or upon the size or extent of a system.

Intensive property: An intensive property is independent of the amount of mass and may vary from place to place within the system at any moment.

Temperature, pressure, specific volume, and density are examples of intensive properties.

With the word "Independent”, this means that one property of a pair can be changed without affecting the other.

Since we know the density and the specific volume of a simple compressible system and they are intensive and independent properties we don't need more properties according to the State Postulate.
