For real gases, Z can be greater than or less than unity. The farther Z is away from unity the more the gas deviates from ideal gas behavior.

The value of compressibility factor for an ideal gas may be:1. Less o...
Explanation:
The compressibility factor, denoted by Z, is a dimensionless quantity that relates the behavior of a real gas to that of an ideal gas. It is defined as the ratio of the actual volume of a gas to the volume it would occupy if it behaved ideally at the same temperature and pressure.
1. Less or more than one:
The compressibility factor can be either less than one or greater than one. If Z is less than one, it indicates that the gas is more compressible than an ideal gas. This means that the gas molecules are experiencing attractive forces, causing them to come closer together and occupy less volume than expected. On the other hand, if Z is greater than one, it implies that the gas is less compressible than an ideal gas. This suggests that the gas molecules are experiencing repulsive forces, causing them to occupy more volume than expected.
2. Equal to one:
When the compressibility factor is equal to one (Z=1), it means that the gas behaves ideally. In this case, the gas molecules do not experience any attractive or repulsive forces and occupy the same volume as an ideal gas at the given temperature and pressure.
3. Zero:
The compressibility factor cannot be zero. Zero volume would imply that the gas molecules have no volume, which is not possible in reality.
4. Less than zero:
The compressibility factor cannot be less than zero. Negative values for Z would indicate that the gas has a negative volume, which is physically impossible.
Correct answer:
The correct values for the compressibility factor for an ideal gas are options 2 only, i.e., equal to one (Z=1).
