Answer» <P>At high pressure REAL gases are less COMPRESSIBLE in comparison to ideal GAS `H_2` and He are more compressible than ideal gases at all pressures Except `H_2` and `He`, the compressibility factor is less than unity for all gases at low pressure The compressibility factor of real gases is independent of temperature Solution :a) At high P, Z > 1 = less compressible b) `H_2`, He have Z > 1 c) At low, `P ,Z < 1`= mole compressible d) Z depends on T.
