Question

At absolute zero the rms speed of gas molecules is​

Answer 1

The rms speed of the molecules of a gas in a vessel is 400ms−1.


The root-mean-square speed is the measure of the speed of particles in a gas, defined as the square root of the average velocity-squared of the molecules in a gas

Answer 2

Given:

Temperature, T = 0 K

To Find:

The Root Mean Square speed of the gas molecules.

Calculation:

- The formula for the Root Mean Square speed of the gas molecules is:

v (RMS) = √(3RT/M)

⇒ v (RMS) ∝ √T

⇒ At absolute zero, i.e., T = 0 K, we have:

⇒ v (RMS) = 0

-So, the RMS speed of gas molecules at the absolute zero temperature is ZERO (0).
