Root mean square velocity of a gas is directly proportional to the absolute temperature of the gas.

Explanation

To solve the question regarding the relationship between the root mean square (RMS) velocity of a gas and its absolute temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding RMS Velocity**:
The root mean square velocity (VRMS) of gas molecules is a measure of the average velocity of particles in a gas. It is defined mathematically as:
\[
V_{RMS} = \sqrt{\frac{3RT}{M}}
