Thermodynamic Properties

A property is any characteristic of a Thermodynamic System.

• Extensive properties depend on the size of the system

  • Mass, $m$
  • Volume, $V$
  • Energy, $E$
  • Entropy, $S$
  • Number of molecules, $n$

• Intensive properties are independent of the mass of the system

  • Temperature, $T$
  • Specific volume, $v=\frac{V}{m}$
  • Specific energy, $e=\frac{E}{m}$
  • Specific entropy, $s=\frac{S}{m}$
  • Molecular weight, $M=\frac{m}{n}$
  • Pressure, $P$
  • Density, $\rho =\frac{m}{v}$

• Enthalpy

• Two-Phase Mixture Quality
