Dominance of strong repulsive forces among the molecules of the gas ( Z=Z= compressibility factor)

Options

  1. Adepends on ZZ and indicated by Z=1Z=1
  2. Bdepends on ZZ and indicated by Z>1Z>1
  3. Cdepends on ZZ and indicated by Z<1Z < 1
  4. Dis independent of ZZ.

Correct answer

B. depends on ZZ and indicated by Z>1Z>1

Step-by-step solution

When the value of Z<1Z < 1, it is due to attractive forces between molecules. At high pressure, when Z>1Z>1, it is due to repulsive forces between electron clouds of the molecules of gases.
