The critical temperatures of carbon dioxide and methane are `31.1^(@)C` and `-81.9^(@)C`, respectively. Which of them has stronger intermolecular forces and why?

Explanation

To determine which gas, carbon dioxide (CO₂) or methane (CH₄), has stronger intermolecular forces based on their critical temperatures, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Critical Temperature**:
- The critical temperature (Tc) is defined as the maximum temperature at which a substance can exist as a liquid. Above this temperature, the substance cannot be liquefied regardless of the pressure applied.

2. **Identify Given Values**:
...
