Under conditions of equal reduced pressure and equal reduced temperature, substances are said to be in the 'corresponding states'. At equal reduced conditions i.e., at the corresponding state, the ____________ of different gases are nearly the same?
Correct answer: A. Compressibility
- A. Compressibility
- B. Molecular weight
- C. Humidity
- D. None of these
Explanation
The corresponding-states principle states that fluids at equal reduced temperature and pressure have approximately equal compressibility factors. Molecular weight and humidity are not universal corresponding-state properties.
