Which of the following is not an equation of state ?
Correct answer: B. Clausius-Clapeyron equation
- A. Bertholet equation
- B. Clausius-Clapeyron equation
- C. Beattie-Bridgeman equation
- D. None of these
Explanation
The Bertholet and Beattie-Bridgeman equations relate pressure, volume, and temperature and are equations of state. The Clausius-Clapeyron equation describes vapour-pressure or phase-equilibrium behaviour rather than a general P-V-T equation of state.
