## Frequently Asked Questions

How do you find the average velocity of a gas?

As per kinetic theory of gases, each molecule is moving with altogether different velocity. Let ‘ n ‘ molecules be present in a given mass of gas, each one moving with velocity v 1, v 2, v 3 … v n. The average velocity or U av = average of all such velocity terms. The root mean square velocity of a molecule can be obtained by using the formula

What is the root mean square velocity of a gas?

Gases consist of atoms or molecules that move at different speeds in random directions. The root means square velocity (RMS velocity) is a way to find a single velocity value for the particles. M = mass of a mole of the gas in kilograms. Really, the RMS calculation gives you root mean square speed, not velocity.

What is the average velocity of an oxygen molecule?

Oxygen gas (O2) is comprised of two oxygen atoms bonded together. Therefore: Convert this to kg/mol: Answer: The average velocity or root mean square velocity of a molecule in a sample of oxygen at 0 °C is 461 m/sec.

What is the average velocity of a molecule in a sample?

Answer. The average velocity or root mean square velocity of a molecule in a sample of oxygen at 0 °C is 461 m/sec.
