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 velocity (Vrms) of ozone (O₃) in a closed vessel at a temperature of 20°C and a pressure of 82 cm Hg, we can follow these steps:

### Step 1: Convert Temperature to Kelvin
The temperature given is in Celsius. To convert it to Kelvin, we use the formula:
\[ T(K) = T(°C) + 273 \]
Substituting the given temperature:
\[ T = 20 + 273 = 293 \, K \]
