Does RMS velocity depend on moles?

The rms velocity is directly proportional to the square root of temperature and inversely proportional to the square root of molar mass. Thus quadrupling the temperature of a given gas doubles the rms velocity of the molecules.

Does number of moles affect speed?

The average speed of a gas depends on its molar mass—the lighter the mass, the faster the average speed.

Is rms velocity depend on pressure?

Root mean square velocity does not depend upon pressure.

How rms velocity of gas molecules depends upon temperature?

So, for a given gas ˉc∝√Tandcrms∝√T i.e., average velocity or root mean square velocity of the molecules of a given gas is directly proportional to the square root of absolute temperature of the gas. It seems from these two relations that ˉc or crms depends on pressure of the gas.

What is RMS velocity of gas?

Root mean square (R.M.S.) velocity of a gas is a square root of the average of the square of velocity. As such, it has units of velocity. R.M.S. = M3RT. where R = gas constant, T = temperature (in K), M = molar mass of the gas.

On which of the following RMS velocity of gas depend?

Temperature and molecular mass of gas.

Which of the following is incorrect RMS velocity depends upon?

Answer: RMS velocity depends upon Molecular Weight.

What affects speed of gas particles?

The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas. In other words, as the temperature of a sample of gas is increased, the molecules speed up and the root mean square molecular speed increases as a result.

How will a velocity of a gas molecule vary if its molecular weight is increased?

Gases composed of lighter molecules have more high-speed particles and a higher urms, with a speed distribution that peaks at relatively higher velocities. Gases consisting of heavier molecules have more low-speed particles, a lower urms, and a speed distribution that peaks at relatively lower velocities.

When pressure is increased upon a gas at constant temperature then the rms velocity?

the RMS velocity remains the same.

What is the relation between rms velocity and average velocity?

RMS velocity = Average velocity > Most probable velocity.
