Explanation

To understand what it signifies when the compressibility factor (Z) for a gas is less than one, we can break down the concept step by step.

### Step-by-Step Solution:

1. **Definition of Compressibility Factor (Z)**:
- The compressibility factor (Z) is defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.
- Mathematically, it is expressed as:
\[
