Critical compressibility factor for all substances
A
Are more or less constant (vary from 0.2 to 0.3)
B
Vary as square of the absolute temperature
C
Vary as square of the absolute pressure
D
None of these
Correct Answer: Are more or less constant (vary from 0.2 to 0.3)
Since at reduced conditions all the substances behaves more or less same we can say that the critical compressibility of two substances is also more or less same.
