Consider the maxwellian distribution velocity of molecules of an ideal gas in three dimension.Let Eav and Erms denote the average energy and the root mean square energy respectively . The magnitude of the ratio Erms/Eav is ?(upto 1 decimal place )

Explanation

To solve the problem, we need to find the ratio of the root mean square energy (Erms) to the average energy (Eav) for an ideal gas in three dimensions. We will follow these steps:

### Step 1: Write down the expressions for Eav and Erms
- The average energy (Eav) of an ideal gas in three dimensions is given by:
\[ E_{av} = \frac{3}{2} k_B T \]
- The root mean square energy (Erms) is given by:
