Chemical Engineering Thermodynamics

Which is a state function?

  • A. Specific volume
  • B. Work
  • C. Pressure
  • D. Temperature
Answer: Option B.

State Functions. The thermodynamic state of a system refers to the temperature, pressure and quantity of substance present. State functions only depend on these parameters and not on how they were reached. Examples of state functions include density, internal energy, enthalpy, entropy.
So, the correct answer is pressure and temperature.
