Calculate the root mean square velocity of ozone kept in a closed vessel at `20^(@)C` and `82 cm Hg` pressure.

Explanation

To calculate the root mean square (RMS) velocity of ozone (O₃) in a closed vessel at a temperature of 20°C and a pressure of 82 cm Hg, we will follow these steps:

### Step 1: Convert Temperature to Kelvin
The temperature in Celsius needs to be converted to Kelvin using the formula:
\[ T(K) = T(°C) + 273.15 \]
Given:
\[ T = 20°C \]
So,
...
