If three gas molecules have velocity `0.5`, `1` and `2 km//s` respectively, find the ratio of their root mean square speed and average speed.

What is the ratio of root mean square speed and most probable speed?

Four molecules of a gas have velocity 2, 4, 6 and 8 kms^(-1) , respectively. The ratio of their root mean velocity and average speed is :

The root mean square speed of gas molecules

If C_(1), C_(2), C_(3) ......are random speed of gas molecules, then average speed C_(av)= (C_(1)+C_(2)+C_(3)+...C_(n))/(n) and root mean square speed of gas molecules, C_(rms) = sqrt((C_(1)^(2)+C_(2)^(2)+C_(3)^(2)+...C_(n)^(2))/(n)) =C . Further , C_(2) prop T or C prop sqrt(T) at 0k, C=0 , ie., molecular motion stops. With the help of the passage given above , choose the most appropriate alternative for each of the following question: If three molecules have velocities 0.5, 1 and 2km//s , the ratio of rms speed and average speed is

If three molecules have velocities 0.5kms^(-1),1kms^(-1)and 2kms^(-1), the ratio of the rms speed and average speed is

If three molecules have velocities 1kms^(-1),1kms^(-1) and 1kms^(-1) , the ratio of the rms speed and average speed is:-

The speed of four gases molecules are 1 km/s, 3 km/s, 5 km/s and 7 km/s respectively. The difference between the R.M.S. speed and average speed is

Four molecules of ags have speeds 1,2,3 and 4 km//s .The volue of the root mean square speed of the gas molecules is
