Calculate average kinetic energy of `CO_2` molecules at `27^(@)C`.

Explanation

To calculate the average kinetic energy of CO₂ molecules at 27°C, we will follow these steps:

### Step-by-Step Solution:

1. **Convert Temperature to Kelvin**:
- The temperature given is 27°C. To convert this to Kelvin, we use the formula:
\[
T(K) = T(°C) + 273.15
