Which of the following has maximum root mean square velocity at the same temperature ? Thus ,
H2 gas with the lowest
molar mass the maximum rms velocity.
Which of the following has highest root mean square velocity?
H2
has the maximum RMS velocity.
Which gas will have the highest root mean square velocity at the same temperature?
| Gas Molar Mass u (root-mean-square speed in m/s) | H 2 1966 | He 4 1390 | H2 28 525 | O2 32 492 |

What is the root mean square of velocity?
RMS Velocity
The root-mean square (RMS) velocity is
the value of the square root of the sum of the squares of the stacking velocity values divided by the number of values
. The RMS velocity is that of a wave through sub-surface layers of different interval velocities along a specific ray path.
Which is correct formula for root mean square velocity?
It is represented by the equation:
vrms=√3RTM v r m s = 3 R T M
, where v
rms
is the root-mean-square of the velocity, M
m
is the molar mass of the gas in kilograms per mole, R is the molar gas constant, and T is the temperature in Kelvin.
Which gas has maximum velocity?
The rms speed of a gas is given by 3 R T M o . Since
hydrogen
has the lowest M
o
compared to other molecules, it will have the highest rms speed.
Which one of the following is the most probable speed?
The speed at the top of the curve
is called the most probable speed because the largest number of molecules have that speed. Figure 1: The Maxwell-Boltzmann distribution is shifted to higher speeds and is broadened at higher temperatures. from OpenStax.
Does root mean square velocity depends on pressure?
Root mean
square velocity does not depend upon pressure
.
What is the rate of diffusion of gas?
Graham’s law states that the rate of diffusion or of effusion of a gas is
inversely proportional to the square root of its molecular weight
.
What gas has the greatest kinetic energy?
Hence, the greater the temperature of a gas, the greater the average kinetic energy of the gas molecules. The temperature (30∘C) ( 30 ∘ C ) of
Ne gas
is the highest in the list of the given gases. Hence, we can conclude that the average kinetic energy of the Ne gas is the greatest.
What is the most probable velocity?
The speed travelled by the number of gas particles at the same temperature is known as Most Probable Speed. Most Probable Velocity thus, can be defined as
the velocity with which the maximum number of the particles in a gas move at constant temperature
.
Why is root-mean-square used?
Attempts to find an average value of AC would directly provide you the
answer zero… Hence, RMS values are used. They help to find the effective value of AC (voltage or current). This RMS is a mathematical quantity (used in many math fields) used to compare both alternating and direct currents (or voltage).
What is the formula of most probable velocity?
The most probable velocity at which the most molecules in gas travel. The first distinctive velocity is easiest to estimate and term as the most probable velocity. The formula for most probable velocity is,
Mp = √(2RT/M).
What is rms velocity Class 11?
Root mean square velocity (RMS value)is
the square root of the mean of squares of the velocity of individual gas molecules
. … Average velocity is the arithmetic mean of the velocities of different molecules of a gas at a given temperature.
What is the purpose of rms velocity?
The root mean square velocity is
the square root of the average of the square of the velocity
. As such, it has units of velocity. The reason we use the rms velocity instead of the average is that for a typical gas sample the net velocity is zero since the particles are moving in all directions.
How do you calculate IRMS?
- root mean square: The square root of the arithmetic mean of the squares.
- rms current: the root mean square of the current, Irms=I0/√2, where I0 is the peak current, in an AC system.
- rms voltage: the root mean square of the voltage, Vrms=V0/√2, where V0 is the peak voltage, in an AC system.
