Compared to air sound heard is more in carbon dioxide why?

Explanation

To understand why sound is heard more in carbon dioxide compared to air, we can analyze the properties of sound in different media. Here’s a step-by-step solution:

### Step 1: Understanding Sound Intensity
The intensity of sound in a medium can be expressed by the formula:
\[ I \propto \rho C \]
where:
- \( I \) is the intensity of sound,
- \( \rho \) is the density of the medium,
