The RMS velocity of the molecules of a gas is greater than the most probable velocity at the same temperature.

Explanation

To solve the problem, we need to compare the root mean square (RMS) velocity and the most probable velocity of gas molecules at the same temperature.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **RMS Velocity**: The RMS velocity of gas molecules is given by the formula:
\[
v_{\text{RMS}} = \sqrt{\frac{3RT}{M}}
