                |  | For values of compressibility factor (Z) less than 1 the volume of a real gas |  
                | | [A]. | is always greater than the volume predicted by ideal-gas law | [B]. | is always less than the volume presicated by ideal-gas law |  | [C]. | is always equal to the volume predicted by ideal gas law | [D]. | may be less than equal to or greater than the volume predicted by ideal-gas law depending on the nature of the gas |
