Is it possible to cool the gas to 0 K?

Explanation

**Step-by-Step Solution:**

1. **Understanding Charles' Law**:
- Charles' Law states that at constant pressure, the volume (V) of a gas is directly proportional to its absolute temperature (T). This can be mathematically expressed as:
\[ V \propto T \quad \text{(at constant pressure)} \]
- This means that if the temperature increases, the volume increases, and if the temperature decreases, the volume decreases.
